It's probably a good strategy, but Hacker News is a bubble and most people aren't going to do this absent a very hard limit in the app itself (like Path did).

Yes, but this isn't a solution for most people. Most people don't want to do that active gardening. It's like when Google Plus excepted everyone to put their contacts in various circles and keep it up to date.

I'm now building an RSS reader that is specifically designed around the algorithm that learns what sources you like the most. It also slightly adjusts the rankings for high/low frequency feed so subscribing to The Verge won't lead to you skipping updates from some personal blogs.

Yes, but very few people use Feedly, which is why they had to shift to enterprise with trend watching and other tools. Platforms like Inoreader and Feedbin are pure RSS plays and their audience is a good benchmark of how much people actually want this.

If you ask regular people around yourself I'm sure none would recognize the acronym.
