I enjoyed the Linux Counter (http://counter.li.org/) in the early days of Linux adoption and so when we had some free time, one of my team tossed together a little app for registering and counting Ruby users. This is a really simple app with one purpose, and is in no way intended to compete with workingwithrails.com.
It's at http://www.rubyusers.com
If you think it's a good idea, please sign up.
If you think it's a bad idea, then I'm really sorry to have bothered you.
All the best,

I think this should get more lime light and people actually register. I too was excited by http://counter.li.org in my college days. People you use it, join it and promote it :)
