Definitely seen it in the specific subreddits for tools, services and products. You’ll subscribe because there’s a community of your peers, you found them! They’re all doing cool things with the thing you’re using

Then 2 years later the subreddit is basically just another support channel for the most boring entry level questions imaginable on loop

Bonus points if the moderators decide to allow image posts and memes (eg if it was just text before) or some other massive change that resonates only with the newer folks and everyone else leaves.

Now the repeating loop of basic questions are answered by people who themselves came for assistance, who repeat whatever they’ve already read, with no proof or knowledge if it actually works

The example I’m thinking of is /r/Twitch in this case. Had a moment of thinking I’d be a streamer superstar, happens to us all right? Was being told* how to build my audience by people who themselves had no audience. Boshed a quick script together and found the average contributing user had less than 10 concurrent viewers when they go live. Useful.

* Indirectly. I’m aware of the irony/hypocrisy that I was also looking for said basic questions - I was searching for answers not asking :P
