Thanks for the great work! According to Christian the revenue received by reddit per user per year was $1.50 (optimistically). I just set up a donation on liberapay of $15 per year with the idea that if 10% of Lemmy users donate $15 per year then Lemmy will receive the same income per user as Reddit.
Votes being public has made it possible to learn a bit about how people interact with posts. I’ve always used the downvote sparingly and I think that is how most people operate, downvoting only what doesn’t contribute to discussion and upvoting what I agree with. But it seems a minority downvote very frequently. There are some accounts that downvote the vast majority of posts in certain communities. Sometimes these accounts have zero posts and comments. Which is pretty odd - disagreeing with so much while never sharing your opinion.
