I recently came across [this](https://stackoverflow.com/questions/12769982/reference-what-does-this-error-mean-in-php) question. 

It basically boils down to 

1. What is the cause of white screen?
2. What is the cause of X?
3. What is the cause of Y? 

with each question being hyperlinked to an answer and the whole thing being community-wiki.

What's your thoughts on this question? Should we allow such things or should it be broken up more?
