Disclosure: I have 2350 feeds in NewsBlur.
Only from VCs I have more than 200.
And I wouldn't take the claim seriously that Google Reader was fast with that many feeds; I found that GR struggled with that feeds: http://the-digital-reader.com/2012/11/01/i-broke-google-read...
I thought I was information overload with ~150 sites. I hope OP uses the 'focus' features so they can get a modicum of information from those 2350 feeds.
It mainly depends of the feed volume, not how many feeds are you subscribed to. I cherry picked a lot of personal blogs that are not updated often.
Somewhat unrelated, but it would be neat if there was some kind of lost and found for RSS as I have sites from the early 00s that I followed which are no longer updated but I imagine the author just changed their site, etc.
One nice feature of newsblur, which I don't use often and not sure if it is available in other readers, but the intelligence trainer would probably help in instances where you have a lot of sites and don't necessarily bother reviewing all posts.
Maybe I just use RSS readers differently. But if I were just going to periodically review what a site has, I would probably go to the site periodically rather than clutter up my list of feeds.
