Sheesh. How long until WP, with regular, excellent upgrades surpasses Drupal, which is loads more "powerful" but has a much slower development cycle and a lousy, awful UI?

That would seem to depend on what you're trying to build. If you're building a blog, or something else that fits squarely in the WordPress design space, go ahead and use WordPress.

WP has, historically, aimed to solve different problems than Drupal. And I would hope that WordPress doesn't try to become Drupal if the cost is additional complexity, a slower development cycle, and less time to spend refining the documentation and user experience. I wouldn't say that Drupal is more powerful: it's more general-purpose. That is often a source of power, but it also entails being harder to design and develop, harder to use, and very hard to document -- the ecosystem is huge, and diverse, and all the modules evolve at different speeds. To the extent that WP has a tighter focus, they should treasure that feature, and maintain it wisely.

Well-said. I'm coming at this from a media perspective. So the use case is always "online magazine." Right now, I'd go with Drupal for that, since its got features WP doesn't and much better access control. But WP is catching up.....

I find "The Morning After" WP theme, a good online magazine theme. http://code.google.com/p/the-morning-after/

Some yummy changes; particularly the Wiki-like edit tracking.

The wiki-like revision tracker is extremely useful, I'm also a fan of the "press this" feature... its just the name seems a bit odd for the functionality.

I'm looking forward to using that feature above all. It's like having Writeboard built into your blog. Except you can use Markdown instead of Textile!
