Google+ is FB's only real rival atm.
It's a sleeker version, more adult orientated and dare I say intellectual. It's where the bloggers, authors and science guru's discuss their work before feeding it to the masses on FB.
I can't see FB going any where for the time being. It has it's users and abusers I know. One needs to be aware and careful of what one posts though. What is written cannot be unwritten (deleted, yes, but not before everyone gets a copy in their inbox)
So for the time being, I'm more than happy to be part of the FB community and accept the many opportunities that have arisen because of my active membership on FB. I can't wait to be able to share the latest ones with everyone.
Wheee!!
