Eric and David,
I was like you guys for five years.
I finally caved in and signed up to both Google Plus and Facebook.
With regards to Facebook, it's changed my life, for the better. I was staunchly against it, I'm now totally for it.
It's really just IRC with pictures; you're with people you know (family, friends and associates) rather than talking with strangers. So, in a sense, I was already on the social media bandwagon since the mid-90s when I first got online and was addicted to talking with strangers on IRC.
As Les and others told me when I first got on it, you use it how you want to use it. Associate with those you want and don't with those you don't want to.
In some cases, you even lose friends. Just like real life.
Suzy,
Well done.
H
