I'd say Plurk is a GREAT way! Thanks!

Yes, Plurk is. How about hellotxt.com? hits all the networks. Each day someone could focus on one area of the conference w/URL reference.

Do you blog? That's one way to spread the word. Comment on educators' blog posts, then invite readers & provide a link after your comment.

DOH! Just saw blog on earlier plurk; answered my own question. If you put your blog in yr profile info, people can link to it; more readers!
