If you're a nerdy blogging type (or even an uber-cool blogging type) you may be interested in this handy little widget I found. BlogRush goes anywhere on your blog and displays links to similar blogs - but the good thing is everytime someone looks at your site, you earn the right to a link on someone elses site. Plus if you refer new users (like I'm obviously trying to do now) you get link credits from their activity too. Basically, you end up with loads of links to your blog all over the place. It's free, so give it a try... if you want.
