I can just imagine how a google "like" button would be sooooo abused. They just have to keep at what they are doing, keep one step ahead of the spam farms. That's all part of being on top. You're a target for the bad as well as good.
I hope they don't buy twitter or twitter don't sell to them. It's BS that Google buys all the big sites in an attempt to control the ENTIRE internet and us.
They tried to buy twitter recently for 3 billions. Twitter isn't for sale currently. Its owners enjoy working on it more than the money apparently . I don't see why all the fear of google controlling the entire internet. Personally, I wouldn't mind if google was running a world government. Microsoft and Apple on the other hand...
At present many people depend upon the google. I think every one should have to consider about this point.
