It's called NINOFF - which means "No I'm No On Frickin Facebook" (although I clearly am, and I'm guessing most of you are too). It's big sell is it's privacy and lack of in-your-face advertising. You can find out more about that here on their site: ninoff.com
As a blogger I am keen to get in on this, meet other bloggers, and maybe increase my own followers. I'm certainly glad I started using Google+ earlier this year, wouldn't it be nice to add Ninoff to my catchment!
So... Want to sign up as a beta tester? It's simple. Go on over to ninoff.com, read what they have to say, and then down at the bottom of the page is the beta tester sign up (dead simple, just add your email address, and your name if you want to) then sit back and wait for the email.
If you do sign up, I'm on there as "Charlie Walker" (how original!) come and say hi!
