eventually yes. one of these days another social network thats revolutionary than facebook will rise. just like myspace, facebook will be trite.
Facebook i worth $50billion and I don't think Facebook will just let it's ads rot. With that amount of money Facebook has, they will definitely do everything to keep their main source of income alive. I will see alot of changes in their ads section and yes, it's pretty effective. Have been using their ads to build a list.
