According to Steve Rubel at Micro Persuasion, eBay is going for a Web 2.0 trifecta and working on bringing blogs, wikis, and tagging to its auction sellers. Blogs and wikis will be launched at the eBay Live conference later this month and serve a variety of purposes, such as enhancing a store or discussing collectibles. Blogs will be free and each eBay Blog will have a URL like http://blogs.ebay.com/userID. Bloggers can specify "search tags" which are essentially keywords that will help blogs on a particular topic, e.g. Coke memorabilia, show up on relevant eBay searches. And of course, eBay blogs will include RSS feeds. More information on the upcoming features can be found in eBay's help pages: About eBay Blogs and About the eBay Wiki.
