I have been hoping the day would come (and soon) that FB finally screwed itself and it's users one too many times and people flocked to G+. What's really funny is that the 'kids' (according to stats) have fled or dropped FB and it's mostly middle aged folks on it now. When I hear that, I just shake my head and wonder 'Why?'. I would think mature adults would tolerate all the damn spam and stuff that is all over FB a lot less than the kids.
Heh, I went to FB once, to sign up... haven't been back since. I had family members and a few other people suggest that I go on Facebook to keep in touch and vice versa, but it's just not my thing. If they want me or vice versa, there's always the phone or email. Besides, with all the privacy concerns and other complaints I keep hearing about, FB is not a destination I'll go to anyhow.
As for the spam, it could get really annoying, but all mail from FB goes straight to my junk mail and is deleted with one click on 'Empty Junk Mail Folder', so I don't even see it anymore. One time I checked there were 47 emails from FB in just a couple of days, usually asking if I knew this or that person... I didn't, so deleted the lot. I don't bother checking any more. Nothing else goes to that folder so I empty it without even opening it,
