This incident has just shown that Bitcoin is a serious store of value, and hackers are targeting the exchanges because they are the weakest link in the chain. Unfortunately, right now, it's still amateur hour with MtGox running an insecure site and generally lax security practices - vulnerable to XSRF, and apparently they let one of their developers download a full copy of the MySQL database to his home PC which was compromised. Now that there is real money in Bitcoin, the free market should start to weed out the exchanges that have lax security. We already appear to have more professional exchanges like Tradehill opening that seem to take security more seriously.
