While I was writing this, it made me think more about what upvote/downvote really means. In a sense, it is very necessary to downvote the comment which gives wrong/incomplete solution, to enable someone else to come to read the blog know which comment to avoid.

I want to ask everyone, What are your thoughts about this?

If there is any previous discussion about this on CF please link it in the comments. Thanks!

Another side note: We should compile links to introductory blogs, that have information about what blogs are, how to use comments section, guidelines to post/write blogs (including stuff like Asking for help FAQ and Blog formatting tips) for new users. If such a thing exists, please link it too.
