It would be interesting to figure out how to grab "related articles" from other blogs. Tags are how some sites currently do it, but that is with posts from the same author. Everyone uses tags differently and some don't use tags at all. Maybe keyword density? Or I suppose tags could auto-complete to a standard that you set.

Not exactly from "other blogs". I mean, yes, other blogs, but within the same site. YouTube doesn't list related videos from DailyMotion.

I think it's a mixture of similar content + user activity.
