The question Is my resume too long if it's five pages? is basically a forum thread. A general question has been posited and everyone's piling on their personal preferences and experiences rather than answering any questions.
The question is titled "Is my resume too long if it's five pages?" and none of the top voted answers actually address this; the top voted answers are actually great advice about how to tailor your resume and what you should put in your resume. However, they are absolutely worthless to the question as posed.
A recurring problem I see on this site is that answers are upvoted because they're useful, not because they actually solve the stated problem. These posts get popular and get lots of upvotes and attention, but as questions and specific answers they're very low quality.
Questions on this site are supposed to be questions, not blog posts or forum threads. How can we prevent questions like this from degenerating into the general problem (how do I have an awesome resume)?
