OC stands for "original content" and the feature is a hold-over from how mastodon does things. the idea being that you mark it if you yourself made it and are not reposting it.
Yeah but that's just someone manually writing [OC] lol. some subreddits had link flair to mark posts as OC though. Here on kbin we have "link flair" as "badges". but also an explicit "OC" marker feature. Having that OC marker feature is something from mastodon.
This is semantics...people use a convention of [original content] on reddit, whether it's an official implementation or not. It's like before Twitter got official retweets. I didn't realize there was a flair/badge for this on kbin until just now, but it feels like an extension of that manual function. In spirit, it exists on reddit.
Mastodon has neither a formal feature for nor a culture of labelling things as "OC", though. This appears to be derived from Reddit culture, if not Reddit features.
no, the people who started mastodon just have a lot of "tumblr" culture. they also have "trigger warning" options, self-censor/blurred pic options, etc. Just a different culture. A lot of kbin users I'm guessing are ex-redditors where we don't really do that sorta stuff lol.
Reddit has literally none of those features in it's code so idk what you're talking about. Some subreddits used the "nsfw" flagging for self-censor/blur but that's not quite the same thing. "trigger warning" stuff if it was in a subreddit was just manually tagged or used link flair.
Mastodon has explicit technical functionality for these things.
