I only have one theme on the repository. This is mainly because child themes are not currently allowed. The biggest reason it's even on the repository is because I was pretty sure themes would be upgradeable and browseable from the WordPress administration in 2.8. So, I wanted to go ahead and make use of this. It would offer a great way for people using my theme framework to know when an upgrade was ready.

One other thing I failed to touch on in my post was the theme previewer. My theme kind of looks horrendous without any widgets set, at least with the content they have for the demo.

Question: Out of the current top 10 themes, which ones would you use?

Thematic is the only one I'd use.
