I'm playing around with an idea for #hackweek (Jan 7-11, 2013) to pull out the "important" things from your Twitter home timeline. Looking for feedback on what you think would work and/or not work.
A few months ago, I built a prototype that texted you whenever 3 or more people mentioned a @username, #hashtag, or URL within a 3 hour window. It worked pretty well but still had a pretty low signal/noise ratio. First step is to learn to calibrate a trend so that popular keywords only "trend" when they spike more than usual.
