The outcome of this question depends in part on the outcome of Updated: Can we get a blanket disclaimer out of the way?, and I don't know if the latter issue has been completely solved. Nonetheless, I think that this is still an important issue.
I see a lot of disclaimers on answers, generally running along the lines of
I am not your lawyer, nor does my answer constitute legal advice. Seek out a personal lawyer for any legal issues.
Great. But after a while, this gets tiresome. First-time users may not know this, but for most avid users, we get the point after a while. I am continuously tempted to edit these disclaimers out.
Another thing is that legal advice should not be asked for here. If people ask questions that ask for legal advice, the questions will be shut down. This - and additional helpful comments - should help people realize that they will not get legal advice here.
So why should we include disclaimers in answers? Answers should not contain legal advice, and so it should be clear that they do not contain legal advice. Furthermore, if a boilerplate disclaimer is just fine, these disclaimers are completely redundant.
Should people put disclaimers in answers, or not?
I don't think that this is a duplicate of Updated: Can we get a blanket disclaimer out of the way?, because I still see disclaimers in answers. Also notably, the question on Main that jimsug referenced, Does a boilerplate legal disclaimer protect authors of content on a website?, essentially said "it depends". We don't really have a definite decision yet.
