Reply to Subforum or RSS Planet with Playlists of Sets

Since a while I started posting every set I play on my blog and I tag those posts with "playlist". I wonder if it would make sense to setup a subcommunity on here where people can post their playlists. Or alternatively I could setup an "RSS planet" where I aggregate blog posts from various blogs tagged with "playlist".

For an example see http://ifnotwhynot.me/tag/playlist

You can see 2 other "RSS planets" I have setup previously aggregating some DJ blogs posting about digital DJing as well as posting remixes in my signature.
