That's really interesting. I started firetweets by tracking only node.js links. I really like the data driven approach you've taken. Do you plan on expanding to other topics?
edit: You already do track other topics. That's really cool!

It already works for any hashtags or usernames that it encounters, here's #sundaybaconclub http://tagwalk.com/tag/sundaybaconclub
In my experience, I have found Tweet source (web, Tweetdeck, API etc.) to be one of the most effective quality/authenticity indicators.
There is tons of job tweets, but most have "job" in the username and/or app source. Also any app source that contains "bot" or "feed" is most likely safe to ignore.
