I think everyone that selfhost their RSS-feeds have at one point or another thought "now what?".

I have 3 recommendations that might help get you started:

• feedspot is a great place to start to just discover what's out there.

• GitHub releases can be followed as RSS (atom) feeds. This is a great way to keep up with changelogs for services that you selfhost. For example, here is the RSS/Atom feed for Jellyfin: link

• Do you listen to podcasts? These can usually be found as RSS-feeds and is a great way to get your daily dose of news on your morning commute.

Start with Lemmy feeds. Open a community, sort it by, let's say, top-day posts, and copy the RSS button link. Here we are - top posts for 24h for a community you like but in RSS. I am subscribed to Ukrainian National Bank news, Kyiv Subway (Metro) non-urgent news, the news feed of our president, few government ministries. All this is to keep up to date with government regulations. Then there are a few developers and IT and Tech portals with worldwide news for their fields - top for the day, top for the week, and top for the month in separate feeds. Anandtech, for example. I used to be subscribed to a few Twitter accounts by RSS via a RSS-Bridge, but it's gone now. A few vendors for the products I like. A few VR portals as I have an Oculus Quest 2 VR headset. Unraid news, as I own one. Thinking of moving email GitHub releases subscriptions to RSS. I can continue if you want.

I use https://www.talkwalker.com/alerts to setup notifications via RSS on keywords that are interesting to me.

I guess it all depends on what you find interesting. I have the brief extension installed on my browser and whenever I find blogs or people I enjoy if they have an atom/rss feed I subscribe. Over the years you find lots of content.

Some of the random sites I follow:

• https://krebsonsecurity.com/
• https://www.errno.fr/
• https://blog.cmpxchg8b.com/

Look into rss-bridge, spinning it up in docker is a doddle and it lets you turn stuff without a rss feed into rss feeds. Since logging out from reddit I use it to keep track of obscure subreddits in a way more controlled fashion, plus, no doomscrolling or supporting spez. There's a whole bunch of other bridges to explore. You can also convince You-tube to give you a feed instead of following there (even without rss-bridge).

Don't forget that TT-RSS can filter articles for you. Say, for example, that your TV feed had a sci-fi category, and you only wanted to see that. TT-RSS can mark everything else as read (or deleted) so you only see that.

Useful for 'firehose' type feeds where you are only interested in a specific subject.

I found a few through https://ooh.directory/

I have been using FressRSS to capture Twitter RSS feeds via Nitter for local municipal news, events, etc.

Since Twitter has gone off and blocked this from working, my rss feeds will need to be re-evaluated. Had these groups stuck with RSS instead of putting all their faith in social media platforms, their posts would have been immune to this sort of nonsense.
