Facebook does not want me to find friends in my GMail address book

I don’t know when this website-wars will end.
Now, its Facebook.com which has started saying that it can not find friends from my GMail address book.
It does not support the given email addresses.

I am not sure what exactly has happened in recent months, but it feels that Facebook.com has started giving signs of monopoly over the social networking market. Well, one reason could be the 4 years old deal between Microsoft and Facebook; and the former may feel that its time to take revenge.

I would like to remind said social networking websites that no one can control social networking by non-social means.

Have fun with Blogger and FeedBurner!
