All these social networks will die eventually myspace (on life support), twitter, tumblr < one of the main reasons why is because like facebook it's being taken over by 12 -16 year olds who add no credibility to those sites whats so ever.
...I mean really? Why are they even on there? It will go the way of friendster...
Now throw in the egotistical self loathing females looking for some sort of validation from sexually frustrated men who's also looking for some sort of approval.
..Facebook like linkden It does have it's uses like promoting businesses ,volunteering work ect, other than that i don't see no other point to it. That's why I deleted my profile after i realize i had to promote my site through ''it'' which requires me actually being ''on the site'' which i had no interest in. I don't want my IQ to drop after reading someones ''update status'' it's hard enough holding on to what ever i have
I know some people would say ''oh i use it to keep in contact with family'' since the invention of the telephone that doesn't seem like a legitimate purpose for using it.....
