I find it distracting to read through comments and search for answers and to find people being sarcastic or refusing to address the question as answered.
I think there should be ratings on comments, since at times they detract from making useful input. It makes this space more like f***book than a technical resource.
Or, people insert snarkiness and rudeness without consequence. How about staying focused on helping answer questions?
I say this also, given that having conversation through comments is not advised on this site. Therefore, comments should be valuable, otherwise, why have them? This ends up being another version of the wildlands of UUCP Newsgroups, from days gone by.
