I have been using Feedly since Google Reader was shut down. Use it across iPhone, iPad and web. I also use it to capture other articles and bookmarks on my boards.
I have subscribed to Pro for awhile but mostly for search and a few other things. I think they do have feed limits on the free tier.
I’ve tried and used a lot of different readers over the last 20 years but for me the most important is sync of read status across my consumption devices.
I have a lot of feeds across many different categories. HN, lobsters, dotnetkicks and a bunch of other high volume aggregators make up one category. Then I have feeds for startup/VC blogs, engineering blogs, some hyper local stuff, and some other non tech categories I’m involved in (food, wine, etc)
