Turn GitHub into an RSS reader

You may be interested in Osmosfeed: https://github.com/osmoscraft/osmosfeed
It is a static site feed aggregator primarily designed to go with GitHub Pages. I host one to aggregate my own writing on different sites. I think it may fit your use case because your Osmosfeed site itself outputs a single Atom feed. So, for example, if I have an Osmosfeed site that aggregates feeds 1, 2, and 3, the Osmosfeed site has a single feed which will include the three individual feeds. Mine has about 10-12 feeds and it has worked perfectly thus far with no issues. Not sure if it would have problems at higher numbers.
