Yes, we definitely need be. I think we even need to be a little more strict on the quality of answers in general, not only the one-liners. An answer of 4 or 5 lines can be just as bad.
Take a look at these answers to 1 question:
- A one-liner suggesting online shopping (deleted, might be edited since I've talked with OP of this in chat. If it does, feel free to disregard the example.)
- Suggesting a reply to only one of the questions that might be asked with one specific answer
- This one is slightly longer, but has absolutely no explanation of why it works, or why it is suggested
- Althoug the suggestion here is good, there is no explanation why the OP should go LGBT shopping to avoid questions, instead of deflecting them. Basically, this is not answering the question, or doing a frame-challenge. (edited since this was written).
These are just 4 examples, of which the last 2 are upvoted (now at respectively 5 and 21 upvotes, not counting the downvotes). We're having a serious problem here, users aren't taking the time and effort to write good answers that
- Take the question of the OP into account
- Provide some evidence, experience or back-up for their suggestions.
I'm suggesting a harsher approach. If questions reach HNQ, users will see the not so good answers and things will deteriorate from there, because other users think they can gain some quick rep because 'hey, there's a highly upvoted single line/no back-up suggestion here', let's see if I can get away with one as well!
I have picked up my flagging/commenting.
If an answer only suggests 'say this', or 'do this instead' without explanation, I'm casting downvotes and flags to get things deleted. That's the only thing I can do on answers that are upvoted more than downvoted.
If they are downvoted, I'm not hesitating to use my deletion privileges as well.
