Musings about Web 2.0

I'm looking forward to learning about how to better use the electronic tools that are available. For those of you in the Web 2.0 class that are reading this post, I have a few questions:

1. How do you give your blog entries a title? It seems like many of you have already learned this. I assumed that putting my title in the "Labels for this post" box would work, but it doesn't seem to do so. Do I just put the title at the top of my entry? (I'll try that with this post.) Is there another way to assign a title?

Whoops -- I just hit "Preview" and found a place to put a title. Is that how the rest of you do it?

2. When does our Ning start? I'd like to be able to address my questions directly to my fellow students.

3. I've started a Wiki for one of the committees I lead. Everyone on the group agreed that it was a good idea, but very few people have posted to it. I think it's just part of their day to day workflow -- but I'm not sure how to encourage my colleagues to log in regularly and to contribute. I'd much rather discuss questions by email and save the face to face meetings for those items that require that sort of immediate interaction, but the Wiki won't work if people don't look at it and participate. Any suggestions?
