The more I think of it, the more I think facebook won the ultimate internet battle.
My thought reinforced after the pathetic social attempt of google with buzz. Why would I want to socialize outside of facebook ? All my friends and family are in already. Not half of them use gmail / buzz.
I believe entire internet will get into facebook: one login, all sites will be kind of widget / add ons / page / whatever inside facebook. All your friends are already there, they have 400 millions user and growing everyday, who will ever think seriously of creating a significant other social network when all the work of gathering people is already done ?
All the futures amazons and ebays will be built in facebook, or at least, be seriously interconnected with it.
They won the absolute battle of internet and this is why they are worth 15 billions.
What do you think ? I can't think of future internet outside of facebook except for some very specific service.
