Hi,
The Planet software is often used for particular topics or large projects, to collect blogs that post on a particular theme. http://www.planetplanet.org/
I think there are lots of interesting add-ons that could be done for it but so far I haven't seen any. Does anyone know any? (Because of the name, it's kinda hard to search for...)
Like: - for users, subscribe to a planet, but block particular posters (maybe some kind of Greasemonkey script for google reader?) - Statistics for a planet - how long have various blogs been 'members', how regularly do each of them post? Which posters typically get the most comments?
BTW this should have the tag "planet" :)
