> I thought I was information overload with ~150 sites.

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.

That was my perception, a lot of personal blogs, thank you for clarifying.

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be neat if there was some kind of lost and found for RSS as I have sites from the early 00s that I followed which are no longer updated but I imagine the author just changed their site, etc.

NewsBlur has an organizer that provides this exact info. Just sort of last update (or even stories per month) and mass delete. It's somewhat new but it makes a world of a difference. The organizer is on web and just launched on iOS. See http://blog.newsblur.com.

Yes, I think this is one of the issues related to Internet archeology. Not equal but similar to the recovery of Usenet discussions.

But is your intention really to read every post by every site you're subscribed to? Someone subscribed to over 1000 sites isn't trying to avoid missed posts - they're just dipping into the stream of sites they're interested in at any given moment.

Read every post, no. But at least get a general idea of the posts for the sites I subscribe to. There are a couple of sites that I let over lapse, HN is a good example, but for the most part, I atleast read the headlines / tags of posts for sites.

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.

I am in the same boat and I simply quickly go through the 50-100 posts of the sites per day. I actually open maybe 10% in the browser. Following small sites and blogs about your interests gives you the best quality of the web in my opinion.

You can add a lot of low-volume sites without having them pile up too much, also I break out my feeds in groups and that makes them a lot easier to go through.

It's possible that many of those could be discarded without being read. As an example, I'm subscribed to the Best Of Metafilter RSS feed, but if I'm on vacation for a week and come back to over a hundred posts, I just mark 'em all as read.
