Just an FYI, PlanetFleck will be shutting down within a day or two. I post this here because there seem to be four or possibly five people reading it regularly, but I only know who two or three of them are (and one of those is me).
Its original purpose was to give me an aggregated feed of the blogs I read, something available wherever I happened to be sitting (i.e. either here at home, or while at work). Google Reader now admirably handles that task, with more bells and whistles, so the technical and social hassle of maintaining my Planet no longer seems worth the trouble.
