When I buy a share of stock or a corn future, my need to trust the government is minimal. I need to trust the exchange. And the big exchanges have an excellent track record - the exchange rules protect against 400+ years of dirty tricks by participants, and the likes of MtGox have a very long way to go. Attacking the database is just the most obvious and straightforward approach; there are so many ways to participate fraudulently in an exchange, or corner the market, or so many other dirty tricks that become rewarding if bitcoin really takes off.

No, it does so in the opposite direction.
I bid $10. Someone asks $9.99. Obviously we're going to make a deal. There's an overflow of 1 cent- one of us will make 1 more cent than they expected to. Either of us could move, we could split the difference, or we could just set an exchange wide rule for this (say the seller always makes it, or the buyer).
Now add in HFT. Same scenario. The HFT sees my $10 bid before the seller does, and sends a buy for $9.99 exactly to the seller, buying the stock. He then sells to me for $10. He makes that extra penny. Has he helped me? Not at all- he took an average of half a penny from me. Does he help the seller? Nope, he took half a penny from them, for the service of completing the transaction a few microseconds sooner.
HFT are parasites. They provide no value to either side, but make a vig. There is no bid-ask gap that they reduce because the bid is higher than the ask. If it wasn't there'd be no money for them to make. Its immoral, unethical, and ought to be illegal. It also siphons millions to billions from the economy.

Re:Is it? (Score:4, Insightful)
I'm going to ignore your sarcasm, and hope this helps some readers.
There are many potential sellers and buyers. For a given market, at a given point in time: the "bid" is the highest price any buyer is offering; the "ask" is the lowest price any seller is willing to take.
When the bid and ask intersect, people do business. In a "thick" market this happens all the time, and the bid and ask tend to stay very close together. That's great for a casual market participant: you don't need to study the behavior of the exchange in order to get a fair price. If you'd like to buy or sell corn at about $6 per bushel, and the last trade was $6, you can just buy or sell "at market" (just taking the best price at the moment), trade immediately, and not get screwed. You might pay $6.01 or get $5.99, but there's no need to carefully craft a stop or limit order, being careful of which way the market might move, and how long you're willing to wait, and what opportunity you might lose. Further if you accidentally buy 10x what you intended, you can turn around and sell immediately and lose only a trivial amount.
On the other hand, a "thin" market just sucks. If corn is going for about $6/bushel, but the bid is $5 and the ask is $7, it's a real problem for a casual market participant. If you unwittingly accept "market price", you get a terrible deal. To get any kind of fair price, you need to follow trading to know that when occasional trades happen, they're "about $6". You put in a stop or limit order for $6, but the guys sitting at $5 and $7 do nothing but trade this market full time, and they can wait. Let's say you're selling. No buyers for a minute at $6, five minutes, you say heck, maybe I was off a bit, and try $5.90. Still nothing. Eventually someone takes you out at $5.70. Most markets used to trade like that. Great for the investment bank that has a team of full-time speculators, bad for the guy who just needs to sell a couple tons of corn. And heaven help you if you accidentally buy 10x what you intended.
But there's obviously a profit to be made there: buying at $5.70 from the little guy and selling at $6 - the business of "market making". Once you have multiple competing market makers, the game changes. A isn't going to let B buy at $5.70, he'll take it at $5.71, except C will take it at $5.72, and so on, until you can just sell at $5.99 and not worry about it. The minimum profit the market makers will take is limited by 2 things: how fast the market is moving (which creates risk during the time the market maker owns the contract) and the amount of automation available. The reason most markets used to be thin was the lack of automation: unless there was a total of millions to be made in a given market, it's not worth paying someone to become the expert there. But now everything is algorithmic, and there's almost no per-market cost, and bid-ask gaps are tiny almost everywhere.
Sure the intermediary wants a profit- but when every market has multiple competing intermediaries, everyone wins. The more market makers participate, and the more frequently they do so, the less money gets siphoned off on each trade by those guys.

Yes, the US government (and other governments as well) does have a history of shutting down alternative currencies and imprisoning and even labelling the people behind them as terrorists.
On March 18, 2011, after a 90 minute jury deliberation, von NotHaus was found guilty on various counts, including the making of "counterfeit coins" (resembling legal tender coins).

- good, what if somebody had a much longer stretch of time to work out the answers before they could even become questions? It's not like those transactions are random.
This will not work. You cannot compute the answers to unknown questions. The questions are composed of all transactions in recent 10 minutes which are basically input and output addresses signed with unknown private keys. In order to successfully employ 51% attack on bitcoin you must be able to ouperform the rest of the network in real time for at least 10 minutes.

Old news? (Score:5, Informative)
This is semi-old news. Mt.Gox has been under attack for at least a couple of days but they appear to be handling it pretty well. I haven't noticed any problems with using them at least. Trades might be taking a tad longer but nothing big that I can see.
Instawallet, on the other hand, crumbled at least a day or two (I read about it early yesterday morning). Their problem had nothing fundamental to do with BTC but more to do with the unique way Instawallet did business with (I believe) greater anonymity. The whole "we gotta rearchitect this thing" press release was that their fundamental way of doing business made them uniquely targetable by fraudsters, thus they gotta figure out something new.

But a hacker's scam worked, didn't it? But this is problem in general with people and IT systems - common crowd don't even understand how it works broadly, so don't expect them to distinguish simple DDOS or network failure from bank/system going bankrupt, for example. Education and explaining - those can only limit damage in such cases in long term. In short term - be honest and leave yourself emergency information channels open.

The OP is not faulting the BitCoin protocol. He/she is faulting the BitCoin developers/staff/whatever for their deployment architecture choices. After, choosing Instawallet's is/was an architectural choice. For the type of operations BitCoin is aiming for, we are talking architectural options that must accomodate growth into the realms of mega-scale/mega-resilient, ala AWS, ebay or Google.

So please, explain to us how a third party's online wallet service is now a fundamental flaw in bitcoin itself? They made a server that did data management for the user, and thought they had security in place such that their data was unacessible without the proper password. They then were proven wrong. So now they need a new method of storing it (architecture) that is secure.

This has nothing to do with "BitCoin's developers". The "alternative infrastructure" comment applies exclusively to InstaWallet, a provider of "online wallets", which was hardly a major player to begin with, and Mt. Gox wasn't "hacked", they were the target of a DDoS attack which made it difficult to access their web site. That's inconvenient if you rely on them for exchanging BTC and USD and need to do so in a hurry, but there are other exchanges available, and everyone's balances on and off the exchange a

This is NOT a "reminder of how insecure all money is in the computer age". This is a reminder of what a crappy job BitCoin's developers have done. Did you somehow miss the part about the need to develop an alternative architecture before this can be reopened?
The bitcoin developers didn't design MTGox.com or pick the hosting company, genius. They made the protocol, which has thus far been perfect.
