It's nothing fancy, change is already calculated by RT.net so I just keep track of the change values and subtract the previous from the latest to get RH acceleration. You must understand, the app I built really offers very little now at the moment.
The other issue if you're looking to build is that RT only gives us data every hour. Robinhood apparently gives out an API that I suspect could offer more frequent popularity data. The immediate upgrade would be to give a service a timeframe value T and a frequency value F, and create T/F number of scraper slaves, set them to analyze across T time and then set them to execute on a stagger of F time in between. For example, 3600 seconds (1h) timeframe across 60s frequency is 60 bots each tracking data across the past hour, but staggered 1 minute away from each other and reporting results back every minute. That's how I'd like to get my shit running at any rate.

Social media analysis would be cool as hell - it's also very hard. I've been looking around for some good existing libraries.

I'm using a node package for scraping Robintrack, https://www.npmjs.com/package/@joemccann/robintrack-api which has trivialized a lot of the web crawling for me. In terms of populating the graph, that's me being fancy with Angular a-la pic related.
