Ask HN: Why was Google Reader so popular?
Pre-Google Reader, nearly all RSS readers were desktop apps with no synchronisation. Then Google Reader launched, was free, fast, available anywhere, was always up to date with how far you’d read, and came from a reputable household name.
After Google Reader launched, other companies built basically the same thing, and some of them flourished after Google Reader was shut down. But none of them have met all of the above points.
It also let you share content with your google friends before google+ existed. And this is why certain google execs should have been fired quickly.
instead of investing and figuring out a way to get your existing user base to contribute content to your new social network, you kill that user base and say that they have to transition in ful to google+. Instead, people were like "we're all talking about things on facebook, I'll just share the articles there"
google+ should have been a data platform with many different front ends (reader being one of them, the facebook clone being another). Instead they just wanted to make a facebook clone.
