I think lemmy just being very small is what turns this into a problem - by scrolling even a little bit on /all you will probably come across posts from niche communities, which can result in local votes being drowned out by the general audience. Much like I don’t downvote posts in languages I don’t speak, I also don’t see why I’d downvote a post like this where I just don’t care about the post because I don’t care about the whole subject of the community (the only reason I opened the comment section is that I was curious why it had 6 comments). If people do that anyway, it can really stifle community growth by discouraging posters.

I think this is fundamentally different from a post that I do care about that just comea from somewhere I wouldn’t usually be active in.
