Twitter. Squidoo. What to do?

As a relative newbie to the Social media scene, I find myself signing up for every application out there. Unsure of which one will get us exposure, or which ones work, or how many do I need for that matter. For now I'm on:

Twitter or @LotsToLearn for those of you in the know

Blogger

Squidoo

Facebook

LotsToLearn.com of course

You Tube

and most of the other video sites, which show samples of our preschool videos.

I'll keep working my way through the media stuff, and hope to see ya on the other side.
