Re: A quick look at crunchbase and all will be answered..
Given that the typical total VC investment pre dot com era in new software products developed from scratch was in the region of a few million $ max for development plus roll out (maybe double that for hardware) a website like stackoverflow would have been easily doable for a 6 figure seed amount. Its nothing more than a glorified bbs board FFS. That fact that any more money that than was raised tell you all you need to know. It is a dot com scam. Just like all the rest.
In case you are wondering where this VC money is coming from for the dot scams. The money that is not the stuff being printed by the central banks (about $12 trillion+, most BoJ and ECB), which you pay for in long term loss of economic growth, is mostly coming from yield desperate pension and retirement funds. Which you will pay for sooner than you think.
