MySpace and other social-networking sites, beware: Facebook could squeeze you like Wal-Mart has squeezed mom-and-pop shops across America. Even Internet giants such as Google could lose ground.
To be honest I've never seen the reason to have one of those accounts. It's my understanding that more and more advertisements and sales gimmicks are starting to creep in all over those sites. They have to make money somehow.
I've met people I have not heard from for years. If your trying to hide, I would suggest not getting facebook. If not, It's awesome. Note : It's best to create an email account just for facebook, cause you will get an email about all the goings on about everything.
