Twitter...I'm kind of lost....

I joined Twitter and found a few celebrities to follow, and just one of my antique connections. I tried searching for people I know, but I guess I need their emails???
I'm a new Twitterer who is 'twattled'! LOL
As if I need another thing, too! I'm already on upteen ning networks!
I'd better work on my website to try to sell some antiques and vintage!
