OK, so I'm new here, and I don't necessarily know my way around, but:
It strikes me that on a lot of questions, people will answer the question, but post their answer as a comment to the question. Now, as a new user, I don't have the option to do that, but even if I did, I just don't get it -- why not post your answer as an answer to the question???
This mainly irritates me as I'm trying to look for questions that haven't been answered, so it's frustrating when I click on a question with 0 "answers" which has been "answered" already in the comments; but surely there's a wider point about the ways people are using the site?? (which tbf I don't really know about, as I'm new here...)
