I was wondering about (how to deal with) answers like
Had the same problem. Here (random [external] link) is the solution.
Firstly, I do not question the answerer's intention of helping others.
However, answers like that are, in my opinion, not directly helpful as they are mere redirects (possibly to some external blog). If the external site breaks, the article is taken off the web or else, the question remains unanswered. Also, most of the time, these external answers may handle the topic of the question but not the exact question itself and thus don't provide precise solutions.
Should we encourage the answerer to add the appropriate part of the external answer to the (local) answer? Should we (also) vote down the answer?
Furthermore, I was wondering why there is no section such as 'How do I answer' in the faq. Or did I just miss that?
