Plugin Repository Downloads
The one weakness I see of the WordPress SVN Plugin Repository is that there is no way to easily deploy your plugin from that space after you’ve written it.
I susppose that there is some utility in “releasing” your plugins from your own site, but it seems like there should be an easier way to deploy plugins than the currently required process. (Something like: zipping your own working directory, uploading it to your site, telling everyone it’s there and not at the repo even though that’s where the code usually is, blah blah blah…)
