I have posted correct information like that on Reddit and have been downvoted for providing sourced information. That really discourages my participation. Why try?

I have to brag on Lemmy.world.

This place is friendlier, and a much better place to interact with others. Oh, there's still a down-vote brigade, but it's much smaller.

Reddit may still have a huge user base, but it's becoming facebook-esque; that is, people go to it because they know it, and nothing else. This place is so much better.
