Not that I dis-agree, but do you consider facebook a startup? They seem like they've entered out of that phase to me.

I certainly don't - and even though Facebook fell out of the realm of startup, it just bothered me that that poster was downvoted for their opinion whether slightly offtopic or not.

By a loose definition of a startup, I'd say Facebook still is one. They haven't had an exit and took money from DST as recent as last year.
