What type of questions should be asked under the following two tags to avoid closing?
You may use this tag when your question revolves around for example: Where can I find materials to train for ... ? Asking which training course is best for you is off topic or not constructive at best as the answers will be equally valid and only apply to you.
The definition of the tag is quite vague and even questions that don't ask for the best course are closed and deleted. The question that asks for a training or screencast of certain type is sometimes closed and sometimes not.
This vagueness is abused by some users who don't even read the question and quickly close good questions under these tags. I have seen downvoting a question within a few seconds and closing during five minutes. This is the reason, the tags should have better description to warn the askers not to waste their time.
EDIT: I picked up one example showing a contrast
- Good WCF + JSON + JSONP screencast?: correct question
- Do records showing the daily work of programmers exist?: incorrect question. Asked on Stack Overflow, it was downvoted in a few seconds, closed in five minutes, and deleted in a few hours. It was asked again on Programmers with positive interest, but it was closed in a few hours as well.
