RubyPlanet.net is done (for now)
There are other features I could add to this web portal, but I basically did it to "scratch an itch": I wanted a single page summary of what people are writing on their blogs about Ruby - this "blog scraping" is automatic so will take no effort on my part. I did add sections "News" and "Resources" that I have to manually maintain but I have a slick administration web interface that lets me effortlessly modify these sections.
Anyway, I keep my new web portal bookmarked and check it myself a few times a day to get Ruby news. Other people are also welcome to use it :-)
