It is not just Adsense bringing Yahoo and Google closer. They are in mood to connect and interface other services like instant messaging clients.

Expect to chat with Yahoo Messenger friends using Google Talk and vice-versa. After this is implemented, you can chat with Yahoo, Gtalk and MSN (already there) IM friends from Yahoo Messenger.

Here is official Google Press Release “… Yahoo! and Google agreed to enable interoperability between their respective instant messaging services bringing easier and broader communication to users. ”

Yahoo Messenger will become one stop IM client to chat with Yahoo, Google and MSN friends. One real positive outcome whose credit should go to Microsoft’s itching to take over Yahoo. Remember, Worried Microsoft, confused Yahoo & laughing Google!
