I think that I can also vouch for things like discord in the fact that it can bring internet friends.

Though I think that two things that I hate is that information there isn't as structured in the sense that someone might come reading this comment after specifically searching for this topic of comment culture.

But the same couldn't be said for things like online forums and as such I can't shake the feeling that if we all collectively stopped commenting on things, it can really move a lot of discourse away that might influence new generation.

I myself have been inspired many times to try something new or think of some idea because of some idea just to try if that make sense. Or seeing someone post some idea that I like and then reading the comments to find nuanced opinion about and maybe I can chime in sometimes helping it.

I feel like commenting system to definitely be one of treasures like wikipedia although I think that the noise:signal ratio is definitely higher in commenting systems (ie. they have more noise than signal)
