Legal Technology - Twitter Spurns Facebook's $500M Buyout Offer
Looks like Facebook ofered twitter 500 million big boys... so they cant be living on baked beans on toast! Not sure how much the make, anyone else got any ideas? They do have advertising on there. I know Myspace make 25K a day for their homepage takeovers where they change the whole homepage style to advertise a film and that kind of thing.
