Why don't people answer opinion based questions?

Maybe because the good ones are harder :P

Exactly. Almost all the questions on this site are one of two types:

- incredibly easy, trivial, stuff you either just know or can look up online in about 10 seconds. Those get answered.

- very, very difficult, complicated questions requiring a whole essay to answer with any degree of seriousness. Those don't get answered very often because they require expertise or at least some thought, research and work. When they are answered, the answers aren't usually very good.

You can have two things when it comes to information, but never all three:

- free/cheap

- fast

- good/reliable

You want good information fast? It is expensive, not free like this site.

You want good information cheap? Go to the library or do the research yourself.

You want bad or superficial information? You'll find it at cheap, fast sites like this.

This site is best for things that don't happen to be online yet and don't require expensive expertise - like how to fix some particular object or where to buy some product etc. That is stuff some people know and others don't, but simply because of chance experience, not because of research or training. If some reader just happens to know and stumbles across this site, you're in luck. Otherwise, see above.
