If you like to read a lot of open source based planets, then check out my aggregation (and uniqification) RSS feed that I cobbled together in Yahoo! Pipes.
Currently, it grabs from the following:
- Planet GNOME
- Planet KDE
- Planet SUSE
- Graphics Planet
- Gimp Layers
- Planet Inkscape
Any other good suggestions? (:
If you’re interested, you can also check out the pipe’s page too.
Update: I added the feeds suggested in the comments as pipe sources.
