Ok so I've spent a few days doing hardcore cleaning and we have a problem with comments and people misusing them.
People who are too lazy to write a real answer so they write a half finished one that doesn't work or is just some commands out of context. This hurts the site because they're usually incomplete, and more importantly, the community can't downvote them or edit them so we have to flag them, which takes up precious moderator time when they have real flags they can be handling. Many of these comments are even missing links to the proper information.
It's rude, you might as well leave a LMGTFY link while you are at it. We don't leave people links to wrong things on blogs, or say things like "Did you search Google?" because we already know it's probably wrong, that's why we're here! Be better than The Gap.
We have too many experienced users who should know better just responding back and forth in the comments instead of FIXING THE USER'S QUESTION. Any one can submit an edit, if you see a new user struggling take the time to help them out with a quick edit until they learn it, it will improve the site.
(This is an easy one): Instead of asking people to reply with information, instead make it explicit when leaving a comment that you would like an edit, example:
What kind of wireless is it?
Can you  your question to add what kind of wireless card you have?
putting the edit in  will make it a clickable link to the edit page.
(edit_link)? Where is that documented?
