Don't let yourself be discouraged by any of the negative remarks - your site looks promising and you're doing a great service to the community if you investigate the mybitcoin.com incident. This fiasco was probably the worst strike so far against the Bitcoin community as a whole.
It's always easier for people to criticize and leave negative comments than to contribute useful ideas - with an ever-growing community like the one at hand, you'll almost certainly find some negative remarks on any new idea, no matter how great it is.
I thought it might be helpful to start a poll
on how many Bitcoins were stolen in total because not many people are going to be willing to give their real names and addresses out for an official investigation but an anonymous poll could help to give a clearer picture of the incident.
As for your investigation: since we're dealing with an offshore address I wonder by which jurisdiction a possible class action lawsuit would be filed and what this would mean for victims outside that jurisdiction. I'm not very familiar with international law so forgive my lack of understanding. IOW, would a detailed report by some victim outside the US be of any help to you?
