Interesting, are you just doing a search using the twitter api for hash tag #ruby using jquery or a ruby gem? I see I can login to your site with twitter, but that seems to be down at the moment. I guess I'd just like to know generally how this functions as I'm thinking of doing something like this for a personal project.
Thanks for the interest!
We are using Twitter's streaming api, tracking hashtags like #ruby, #rails. Yep Twitter sign in seems to be broken, will fix it asap. Signed in users can reply/retweet.
If you need any help please email me "girish at cuberoot dot in"
