I don't know how much I have to elaborate on this. As the faq says:
Chatty, open-ended questions diminish the usefulness of our site [...]
The faq is pretty straightforward what is considered a good question and what isn't. Despite this when I look at the questions with the most upvotes, 90% of them are exactly like that. Most of the time they violate more than one principle which is exemplified right after the rule itself.
Is the cause:
- Poor moderation? (Users with enough privileges do not care abut this rule?)
- Wrong incentives? (A question like this can get you 3 gold 3 silver 3 bronze medals if survives moderation.)
- Or anything else? (No idea.)
