I found this on another forum and..... It think Google already prepared a shopping list... May be he'll buy Squidoo later on. Haha..
I don't know but the business model and profitability potential of twitter is still in doubt. Why would either of Google and Microsoft risk buying in something that's hard to monetize?
hahaha Google might buy all those wonderful site! Maybe some sites are included to what you had mention.. "It think Google already prepared a shopping list..." Maybe 100+ listed on that shopping list.
