Usually by accident and usually only because results from it popped up in a web search.

Mangled all my old accounts, so never logon and always browse incognito, etc. This is looking to be a great solution to the occasional pop-in I need to do, esp now that they've killed old Reddit for non-logged in users (old Reddit redirect on Firefox for mobile was a huge help until that happened)

I would gladly do that, but there is one subreddit I still patronize infrequently (r/amputee) and for a simple reason: I recreated an identical community here on Lemmy but it has 28 subscribers and I've been pretty much keeping the lights on by myself for the past 3 years. r/amputee on the other hand is active and has 16k subscribers.

If you go to r/amputee, people complain about Reddit. But here's the thing: people are there, so everyone else who has the same problem goes there too, and the vicious circle continues.

That's the social media platform lock-in Cory Doctorow describes in his explanation of what enshittification is: the platform is terrible and everybody wants to leave, but nobody does because nobody else does either, and people stick around because the other people they want to interact with are there too. It takes the platform becoming so exceedingly nasty that everybody leaves at once to break the circle. But Reddit, crap though it is, isn't there yet.

So yes, I maintain a minimal presence on Reddit's r/amputee, while I keep Lemmy's c/amputee going, until such time as Reddit's amputees are fed up and look for an alternative, and they'll hopefully find c/amputee welcoming enough and familiar enough that they won't experience too much trouble switching.
