I don't like Facebook and I don't use Facebook. I don't recommend Facebook to friends or clients, and if you want to go into all the reasons why, then write me and I'll jump up on my soapbox and explain.
I'm not alone in this. Just Google "I hate Facebook" and surf for awhile.
Or don't. Opt for this: over at TechRepublic today, Toni Bowers writes a nice, short article on her take on this issue in "LinkedIn is Facebook's mature older sibling."
And have a great weekend.
