Ok, I signed up for Twitter. Not sure exactly what I am supposed to do but I've done it. Lets see now how it works. I'm not sure how to search for people if I don't have an email address. But I did send invitations to people in my address book. So far so good. If anyone wants to invite me to follow them please do so. I'm so connected now with LinkReferral, LinkedIn, Twitter, Blogs, Etsy, etc I can't imagine how I could ever feel alone again. LOL.
