... like mine (gemcast, which is written in Ruby), is that it's filesystem-based. Doesn't sound very impressive, but because of the filesystem approach, it took me only about 10 minutes to hack together a little cron job to produce the "SpringViz Download Count" sidebar box you see at the right (when you're at the top of the weblog). It updates every 15 minutes. Sweet. The Google referrals item was also done this way.

As a side note, it blows me away that I've been running my blog with gemcast for a year and a half now, and haven't felt a burning need to make do more. I guess I'd really like to have a "single-entry" view, but it hasn't been important enough to get me back into hack mode.
