Firstly, I totally understand people who find reposts annoying and I have blocked few of those because they’re simply irrelevant to me

lemmit online / hackernews reposts

• those help drive inspiration for post making: I can snatch best ideas and post my own version on lemmy
  It’s especially helpful when you’re maintaining inactive community where you’re the only poster. Inactive subs are seen as dead ones.

• not my use case, but I see those instances as ability to combat FOMO for the users who just switched over to lemmy and getting use to its quirks. No need to snoop to reddit if its content is in your feed either way

• if you see lemmit online posts then someone on your instance wants this content/subscribed to it – it doesn’t appear out of nowhere

controversial opinion

tbh I wish each lemmy sub would have its own bot to post content stolen from other places of internet. Almost all popular websites have ones and they do bring large audiences. Be it just memes, science news or animal photos: people stick with a website because they can regularly get their dopamine hit. “Normal people” i.e. lurkers usually don’t care about post originality. People simply want enough good quality content

QoL bots

• tldr bots are generally helpful for long reads\vids and I wish they would be available as option on post creation page
• bots for linking to invidious instances / archive.ph nonpaywalled articles: just saves time

P.S. as a bonus here’s a page about bots that wikipedia uses to streamline and automate work Wikipedia bots - Wikipedia
