Reading this post at "Off the Mark" about the Carnival of the InfoSciences, I realised that I don't keep up with it enough because there is no feed for it. The carnival is hosted by a different blog each time, although some good sorts have hosted it more than once.
So I'm now subscribed to a Bloglines search for "carnival of the infosciences" and I think this will work pretty well for me. In addition to the actual carnivals there will be a few other posts about the carnival but that's OK.
