I wanted a way to keep track of all the best Stacks, Themes, and Plugins that were being released and updated all the time so I started a little site called Weaver News: http://weaver.news
It lets you see the latest and greatest stuff, lets you vote on your favorites, and bubbles up the best stuff to the top. Plus it has a nice RSS feed of all the latest things.
Anyone can post a link. And every vote counts – so vote up your favorites.
