Would you like to "feedfy" internet content?

Hi, I am creating an app where you can turn everything into a feed of its own.. it is very similar to a news aggregator but the difference is that you can aggregate pretty much anything. Let's suppose that you are a python developer and you would like to track all stack overflow, python related questions, python reddit and some other programming topics from some forums.. well, all you have to do is to put some simple css selectors to extract those information and group them in your feed.. the app will make sure to collect and group all the new info to your feed. Other users may want to follow your feed.. there are lots of possibilities but before I can keep going I would like to hear what you guys think. I have a functional prototype but I work as a full time dev.. it is a pain to work on this after working the whole day..
