I’ve started using LinkWithin to automatically add links to related posts on my blog, to make it easier to find posts on similar subjects. (However, you won’t be able to see them if you’re reading using a blog aggregator like Google Reader or Bloglines, or if you have Javascript disabled). Some of the links can seem a bit random, but apparently their relevance should improve over time. Let me know if you think they’re a good idea or just clutter up my blog.
