Though I don't use it for reading HN, I've been using The Old Reader since Google Reader shut down. It's basically a copy of Google Reader as it was.

RSS is pretty much the only way I read HN.

Same. Glancing over 1000 headlines on a fresh pull saves so much time and energy.

The 30 minutes it takes to peruse makes for a good breakfast routine versus only making it 10 to 20 stories deep in the same amount of time.
