Just learned about it last week here on Kbin, because of the Reddit blackout.
I've been feeding a lot of sources to my RSS programs, and just found out a lot of sites either hide or don't have RSS, so that project was enticing.
So I contributed with 4 sources to help it grow ahahah
The decline (and perhaps fall) of reddit put me in the position of needing an Android RSS client/newsreader app for the first time. I want to say I used to use the functionality built into Firefox? Is that right? Anyway, for Android I've been using Inoreader. Seems to work ok. Mostly use it for the AP news RSS feed.
