I built my own reader because I didn't want unread items to accumulate. It just shows what was published the last X days.

The result is that there is no need for persistent storage, so its real easy to host. If you're interested, its here: https://github.com/lukasknuth/briefly

My specific need for RSS is the accumulation. There are people who post once a week and I don't want to miss the posts because I was offline at the time.

I just bought a reseller plan from verpex host for $5/month. Can host unlimited domains and bandwidth with WHM. Access everything through cPanel and ftp. SSH on occasion.

Installed freshRSS in 1 min with softaculous

What the purpose of hosting whole reader instead of local app? Or is that something else/more than reader?

Allows you to check your feeds from multiple devices. For example I usually read from my phone, but sometimes would like to check my feeds from my desktop.

You could just subscribe to the same feeds from multiple devices/apps, but then you have to manually keep track of what's already been read and that will quickly get out of hand.

Synced read state.

If I read from my mobile using NetNewsWire and then go on my laptop and read with the FreshRSS web client, I don't need to wade through a bunch of articles I already read.

Runs 24/7. Also, I already host other things on the server, so there is no added cost.

freshrss is excellent.
