Which ones have you tried? For me, RSS readers are a pretty personal thing, like text editors. People have preferences for how they want to read this stuff.

I haven't used one since Newshutch shut down back in 2009 or so. I can't remember the names of any that I tried except Google Reader, which I used for about... 20 minutes total?

Probably not coincidentally, that's about when I started using HN.

Have you tried The Old Reader (whose blog post you just read)?

I absolutely love it. Unfortunately, I had to give up on using it last week since I had too many feeds to stay on the free version.

I'm now using Digg's Reader and I'm happy so far. Updates more often than (the free version of) The Old Reader too!

InoReader(.com) is the only one I've found post-Google Reader that gets out of my way and lets me read things. The experience on mobile could be improved, but it works well enough for me.

I just use rss2email. Everything I want an RSS reader to do, good MUAs already do.
