Seeing a lot of upvotes on a post or comment feels nice, seeing that mass social approval of whatever my contribution was. But I also never had any interest in engaging in low-effort posts to get that same reward. I also think the Lemmy hivemind disapproves of low-effort posts like that so such behavior would not be rewarded.
I do wonder what motivated people who made low-effort posts for karma, and why I don't seem to see it here even though we share an upvote/downvote system. Identifying that might help us at least figure out what not to do so that we do not set up a system that encourages that behavior. We do still clearly have the ability to see upvotes on posts and comments.
It is also possible I'm seeing low-effort posts but they are not rewarded as heavily and I mentally dismiss it as "just someone trying to get any activity going on the Fediverse at all." I sometimes just post a link and let it be because it's relevant to the community, I thought it was cool, and I'd like to see some Fediverse activity there but don't really have anything original to say. It's possible the low-effort posts are not rewarded not because the Lemmy hivemind disapproves of low effort but because they just don't see it in the tiny little community I posted in that receives maybe an average of 3 upvotes per post.
For what it's worth, I'm not using "Lemmy hivemind" in a derogatory fashion here, I just mean it as "the general sentiment of most Lemmy users".
