Well I finished the fixes to the Weighted Categories (aka tag cloud) plugin. Anyone who cares is welcome to download and use it. Apparently WordPress 2.1 changed the API a little bit (for the better, of course) with respect to getting categories. Instead of calling a obscure function with a bazillion parameters and having to munge its return value with regexes you can now call the handy get_categories function with optional parameters and get back a nice array of objects to use. Its great to see WordPress starting to go completely object oriented.
On a side not I'm working on a new version of the Google Reader Shared plugin and hope to get that out in your hands sometime tomorrow or the day after (still have a few bugs). This version will incorporate some of the work of Jeremy Michelson to allow the plugin to fall back to using cURL if allow_url_fopen is not turned on with your host and also fixes the errors may of you see with functions being re-defined. More details to follow.
