Will, i sent you an e-mail a couple weeks ago, maybe it got caught up in the spamosphere. 

I should have something to show you guys soon and I'll send it to you.

While we are on the subject. 

Does anyone care about Trackbacks anymore considering they are pretty much overrun by spam?

What other features do people like about blogs over regular forums?

I could care less about trackbacks. My main concerns are around traffic and SEO. A blog module needs to ping all the major ping services and should have an option to set up the ones you want to ping. Technorati Tags are a must if you want any decent traffic and it would also be nice if there was a method for claiming your blog on Tecnhorati. This is really a Technorati function, but the blog must conform to their rules or you can't claim it.

Then there are categories, Really need those and ideally they should become part of the URL when the post is viewed on a single page. The title should also be listed as the page name. May not be possible with DNN, but its needed.

RSS is becoming a big part of the web. Feeds need the ability to be run through a service such as Feedburner so you can track your subscriber base.

These are the big ones in my opinion.
