It's funny as a parent, because I'm expected to tell my son that he shouldn't curse even though his mom and I do. And all of our friends. And coworkers. And my boss. And his boss. And our CEO. And the fucking president.
I haven't really had any luck yet. I was a Farker back in the day, but went to Reddit while a lot of other people were going to Digg. Back then I loved Reddit as a social news site, but now I really dislike it because it's mostly a meme and image aggregator. (IMO it was the memes, image macros (Advice Animals) and meta references that killed that site.)
That said, I like PinkBike.com for MTB stuff and Hacker News for tech stuff. Those are really the only two forums where I actually leave comments these days.
That community ate away at my soul. We had a good group of core users, but by my estimate about a third of all submissions were from karma farmers and new users shitposting memes and image macros. (Or people complaining that I wasn't allowing shitposting memes and image macros.)
The Digg migration was the first step towards Reddit's Eternal September, but Covid lockdown was the final nail in the coffin.
I was a long time reddit user (I created my first account in 2007), and I eventually left for this reason.
I moderated a cycling community (r/mtb) that grew to about a quarter million subscribers and I had a really difficult time keeping the low effort content at bay.
When communities grow to a certain size they lose their niche audience, and lowest common denominator posts bubble to the top and drown out quality content.
I had that happen with a sleep tracker for Apple Watch. It was a few dollars for the app, but to actually view the data it tracked while you were asleep, you had to upgrade to the premium subscription. Fortunately it was easy enough to get a refund[1].
Off topic, but where did the "underwater basketweaving" meme (in the traditional sense) come from? My dad used to say that all the time in reference to what he considered frivolous academic pursuits.
I think it depends on the specific Reddit community and how it's moderated. I moderate a community with 80k+ subscribers, and I put a lot of effort into keeping it on topic and interesting. (And we have community flair so users can add something very similar to a profile photo.
It's ridiculous.
