Setting up EARLS
Earls is useful for archiving and counting URLS shared in tweets from a particular hashtag, eg., conference backchat etc. Getting it set up on Heroku (a tiered free service) is fairly straightforward. Getting it to go live requires a credit card tied to your account - but if you're using the free tier, this shouldn't be an issue. Anyway, with the help of Dan Pett I learned how to set one up. Dan set up an earls instance for #msudai.
