To Tweet or not to Tweet--that is the question

If everybody I know tweets, how come they haven't found me and I haven't found them on Twitter?

Okay, I admit it.  I just don't get Twitter.  I mean, I've been on it for like two years, and I don't get it.  I've even taken an online class about it and still haven't picked up the intricacies.

I use Tweetdeck, which seems a lot more coherent than just a plain Twitter account, and this way I can coordinate my various personas.  Nice.  But what am I supposed to tweet?

And it seems like almost all my followers are other authors.  We're all telling each other about our books and not selling any of them.

I find people who tweet constantly to be a real PITA and I unfollow them as soon as possible.  I mean, do I need to know every time they burp or take a sip of Diet Coke?

I'm not saying I'm going to pitch Tweetdeck any time soon, but I don't even log on every day.

If you use Twitter, what do you think the greatest benefit is?

BTW, if you WANT to follow me, I'm @LornaBarrett @LorraineBartlet @LLBartlettbooks
