Sam Ruby has been writing about using a planet-style aggregator to create a feed of what's hot among a community of bloggers (see
MeMeme and
MeMeme 2.0) -- not the big wide noisy blogosphere. Like meme-trackers
TechMeme and
TailRank, Sam's code is based on the idea that an entry that mentions a link is a vote for that link, but unlike those sites only blogs included one planet can cast votes. Cool idea and it seems to produce good results. I'll have to consider it for the next rev of PlanetTool (the
RSS and Atom in Action example (one of the
Blogapps) that I use to generate my
Triangle Bloggers site).
