Facebook is newer then Yahoo and has more things then Yahoo does. The interface is better on Facebook then Yahoo. Facebook is only a Social Networking website not a search engine and it doesn't have as many internet related things that Yahoo does. I personally use Bing as a search engine.
how do i move a picture that was emailed to me at my yahoo account into my facebook profile
Very likely not, because Answers.com (owns and created Wiki Answers is a very large company and so is Yahoo, so they probably won't merge.
i think he has a facebook
disconnect your yahoo account from your Facebook account.
no
no
You click facebook then log in! Boom :)!
As per my knowledge you can use other e-mail id for Facebook such as gmail. So no need to worry about Yahoo.
he owns facebook not yahoo
I'm crazy, still can't do it
Yahoo is mostly a Search engine. I don't think yahoo is ready to take on facebook and googleplus.
