Here’s a Question: Why Does Quora Exist?

The author might have stopped and asked himself/herself: why am I complaining about something I don't have to use?

I like Quora because it has good technical features, has no concept of off-topic (and the annoying busybody moderators that come with it), and has a highly educated userbase.

Quora exists because people use it. If you don't like it, don't use it, end of.
