Is StackOverflow.com the last newsgroup we will ever need?

I’m very impressed by www.StackOverflow.com.  The site is similar to a newsgroup and accepts posts on all things related to software development.  However, unlike traditional newsgroups that are segragated by topic, StackOverflow uses tags for each post.  This allows a single post to be grouped into multiple topics; which is more convenient for posters than posting the same topic in several traditional newsgroups.

But the benefits don’t stop with the tags.  StackOverflow.com also provides a rating and feedback system.  All users can judge the answers and your contributions count toward your overall site score.  I’ll bet this makes the site a little more fun and encourages use in order to increase your total score.
