I just added a couple more feeds to the Christopher Planet! RSS feed: one from my ClaimID page, which shows recent changes, and one for my latest events at Upcoming.org. I haven't actually added them to the site proper, that will happen eventually once I settle on a better layout. I'm still messing around with it on my local development site.
Oh, and if you've already subscribed to the feed, you may need to re-subscribe for the other two feeds to show up.
