For years (since the demise of Google Reader) I’ve been using feedly.com (which is free) as the source for my RSS feeds but I never actually use the web client. I use native clients that integrate with Feedly. For iOS I use Reeder ( https://reederapp.com ) but for Mac (which Reeder also supports) I use the excellent ReadKit ( https://readkitapp.com/ ). Most blogs still appear to support RSS but you do get the odd one…
Interesting, I also migrated to feedly but I do use the web application on the desktop, though the feedly app on my phone. On desktop, the webapp works really well for my purposes — which is mostly going through all updates (all sorted by oldest, "j" for next), and once in a while opening one in a full browser window ("v") or sending the page to instapaper.
