Yesterday Ericb ask in this thread [1] about interesting gists. A while ago I built GistCube [2] as a weekend project but I never announced it.
GistCube is a tool to discover, share and organized interesting gists. It also provide Rss for any selected tag, but so far only I am using it.
Maybe some else, beside me, find it useful.
