I self host FreshRSS and among the many sites I subscribe to, I also subscribe to quite a few hashtags on Mastodon which I'm aware isn't highly publicised so not everyone knows you can do that.
If someone reads this comment that didn't know you could do that -
(Set your purge limits aggressively, because despite people suggesting otherwise, you will very quickly have thousands of unread articles to trawl through)
#android#fediverse#homeassistant for my interests - and #introduction to make sure that I see and boost plenty of newcomers to get them a good start on the fediverse. It's introduction in particular that requires a very aggressive purge policy! I only keep I think 50 introduction posts across 3 days, but even then - my FreshRSS is typically 1200 articles on a daily basis.
Excellent! If you looking for an Android app - although the PWA is pretty good too, Readrops is what I use, because it supports the GoogleReader API that FreshRSS exposes.
