I host Tiny Tiny RSS.

• my list of subscriptions and lists are centralised so I don’t have to set this up on any other device. I can access this on my phone, tablet and PC.
• it synchronises read/unread stories across devices so I don’t have to keep sifting through the same articles I’ve seen.
• I’ve got a long list of blacklisted words. I don’t want to hear about sports news, gossip, USA-centric news, “he said/she said” bullshit from social media that mainstream news seems to love to report, etc. Now I can set up my blacklist in one place an it carries over.
• there are a lot of great apps that will access the server RSS feed. I’m never actually going to to TTRSS browser page.

The point isn’t to download content to the server at all. It’s to keep the centralised list. I host opodsync (Gpodder podcast server) for the same reason.
