We’re experimenting with a new system for connecting bloggers across WordPress.com with people writing about the same topics. We just turned on our global tags system, which means that when you blog about topic X and tag your post with X, you can see everyone else who has done the same. Think of it like Technorati tags for our little community here.

You can browse a zeitgeist of what’s popular in the last 48 hours here or you can type any tag into the URL to browse those posts.

You can begin exploring on tags like culture, politics, blogging, life, or apple.

Over time these should start to drive more and more traffic to blogs that utilize categories.

Let us know any ideas you have for new features along these lines.
