I recently read a post on MixedMarketArts that talked about how to get external links for your blog. There was one site in particular that I found to be quite interesting. The site is www.rsshugger.com. This particular site allows bloggers to promote their blogs via a rss feed. Not only that, but it's geared to bringing readers and bloggers together. Personally, I couldn't resist the opportunity to get signed up.  As a matter of fact, I think you should too.  BTW - It's free!!!
