Active userbase is valued higher than technology... Twitter, Digg, Youtube... all those are free, easy to replace and for from exciting technology, but they are worth billions when you figure out how to monetize them properly. Everyone could build a twitter/digg/youtube clone, but you can't clone a userbase.
Having that said, they numbers these companies are potentially worth don't mean anything when they don't sell... So far Twitter is just a site making no money at all having huge scalability problems and they might just die out owing money to their investors because they have no clue how to turn their userbase into dollars.

Nah,with the extremely low rate people respond to spam you wont get your money back that way. Besides, the real big spammers send out way more emails than that daily and they just have to pay some kid for that to write a vrirus and create a huge botnet
