Tragically, no. After Google killed Reader, I (amazingly) couldn't find another client that didn't have some fatal flaw that didn't make it not worth the bother. I now use the dumb, low-tech solution of having a few folders of bookmarks of sites in various categories, which I'll occasionally check using "Open in Tabs". Lamentable
At one point, I was building a service that allowed you to build digests of collections of feeds and presented the articles in a reddit-style view. Additionally, if others had the articles in their digests, it added a comment section. Is this something you would use? I had trouble gaining traction with the service and shuttered it, but I think about starting it again often.
Honestly, I think momentum has shifted, mostly to twitter, w/ people either posting content directly there or linking to medium, and occasionally, personal blogs.
But Twitter is flawed (if for no other reason, than because they are increasingly exercising editorial control). I look forward to whatever replaces it...
