Are you sure this is true? RSS failed because people stopped using feed readers. I stopped using a feed reader because there was an explosion of content and managing with a reader just didn't scale. I was happy to outsource curation. It was a "hair on fire" problem
This was my experience as well. Opera 12 was my browser of choice because of the built-in feed reader. There were several times where I exported my feeds to an .opml file and started over, because I was inundated with updates and following way too many blogs.
I still have these exports, backed up to a CD somewhere.
Yes. After my comment I started thinking more about the experience at the time. It was always fun adding new feeds until you have too many. The hard word comes at deciding what to prune. It isn't even just about time, it's about not being able to figure out what to get rid of. Like a closet filling up with clothes and you wear them all. You know you just can't add more but figuring out what to unload is painful. Maybe this is a good case for clothing rental services.
Edit: actually I would say its more like an infinite closet but the more clothes you had the longer it takes to find something to wear the next day until things becoming unbearable and you just close the door to your closet, lock it and then rent clothing for the rest of your life.
This is true, but there was no reason that RSS readers themselves could not present you with a curated feed built both out of your subscriptions as well as global feeds, imitating what Twitter already does.
I dunno, I fetch roughly 10 per second which isn't a lot. It takes less than an hour to fetch 30 000. If one would do a bit of logic based on pubDate intervals and slow the process to 24 hours you could "hammer" a sub set more aggressively and still be fine on a modest desktop.
