The reference is for Gavin, but the feature is for everyone. If you're not someone who lives entirely in a feed reader, you may have noticed something neat on
Gavin's site or, more significantly, on
Engadget. Instead of a list of recent posts after the post content (and ad), you'll see a list of
related posts.

A lot of people have mused that other blogging systems have had this feature for a while, but we were just holding out for one worthy of
our blogging system. Not just based on tags, categories, or titles, these links combine tag frequency, post date, and a slew of other criteria into a complex algorithm that I can't begin to understand. But it works. And hopefully, it'll drive traffic around different parts of Engadget and other sites. So... go check it out and enjoy the wanton surfing that's bound to ensue.
