The gamespot RSS feeds for blogposts do not include the Category or the Tag values that are being accepted in all blog posts now. Not sure what use these things are put to, if anything - at the moment. Hopefully, TV.com will be carrying these RSS feeds directly soon, and include the values from these fields. By the way, if you have not looked into RSS - you should check it out. It is a pretty handy technology. You could use it to keep track of your own blog posts, or other people's, for instance.
