That's the problem - I couldn't find the information I was looking for at the site. It took a leap of faith to sign up to find the FAQ, expecting that the interface for registered users would be more complete; exactly the same problem you were trying to solve when removing mandatory signup.

The only parts of the site that should be hidden behind the sign up process are those that only affect logged-in users; learning about the site and business is not one of those. Most of that information does not need to be located at the front page itself, but there must be a link allowing the user to find it.
