Are you collecting data for a scream-detection service?

I built https://reviewsignal.com which aggregates twitter opinions about web hosting companies. It runs it through spam filtering and sentiment analysis to constantly give an updated view into what people think about these companies. It makes money with affiliates, most hosting companies have them, some don't (eg. amazon). I don't let affiliate program existence or pay influence the rankings, it's just pure data. It updates itself and has for almost a decade now.

Also, because my app uses API Gateway and Lambda as a backend, Amazon gives me a $100 credit on my AWS account every month to cover the costs. My costs for the app a…

The second part of your comment made me curious, cause I use AWS Lambda a lot. No extra credits for that... was that a limited time event or regional?

I created this online graphing tool in 2007 and haven't updated it in years: http://fooplot.com/ It's still generating a small amount of ad revenue every month. It used to generate 5-10X what it does now before the days of mobile apps. Back then it was a very meaningful addition to my grad student salary. I had 250K MAU at one point, many of which seemed to be coming from middle and high schools in lower income place…

I remember using that a few years ago! Was a great little tool, thanks for making it!
