it is very interesting about Mark. Facebook vs. Google batle is keep going. Microsoft with Bing search engine is also involved in that battle.
It looks like we have "unification" of firms...Microsoft , for example looking for stronger partnership with Nokia. They also bought Skype. Google on the other hand, have youtube, picassa and blogger.com , among everything else.
Google also looking for strategic partnership with some big cell phone company. It would most possibly be samsung, beacuse of android.
Facebook is playing some wird strategy. is it best por worst strategy ever seen, we'll see - facebook made some strategic partnership with microsoft, but not directly..they sign some contract with skype, as i heard. they are advertising it like- "best social network with best video chat client software"...and it can be very good .
Dunno, they are big players, we'll see whats up in future..
