I've noticed that the demise of twitter has impacted my ability to connect with like minded people - I gave up on mastodon because the ability to stumble upon other people with similar tastes wasn't nearly what I wanted it to be.
Here (HN) I have mostly found wonks and trolls replying directly to me, but I do see a lot of interesting discourse (which is what I'm looking for... right) which will likely lead to connections (eventually)
