This is crazy. Can someone reproduce this behaviour?

The fact is that there is some useful info that only is on Reddit.

I mean reddit has become a insanely huge knowledge base for all sorts of technical problems and other topics. I’ve searched with site:reddit.com so many times for problem solving.

Muscle memory is also hard to break. I had to remove Apollo from my homescreen :D

It definitely is worth it. In terms of the number of users, it certainly cannot be compared with Twitter. Measured in terms of interaction, meaningful exchange and a nice community, it is worlds better than Twitter.

There are topic-oriented instances, e.g. for cybersecurity (https://infosec.exchange/). But of course you can follow people from other instances through the federation. The advantage of topic-oriented instances is that you have a local timeline on which all posts of your instance appear.
