Facebook - should my business have a FB page?

We can't avoid the ubiquitous Facebook and other social media. Even if you don't join up, chances are most of your friends do.

What can Facebook do for your business - is there any point in going to the trouble of setting up a Facebook page? Who, besides your friends, is going to see it?

Honestly,i know people only using facebook for their businesses,and get by very well.you can reach a wide audience,and numbers grow fast. The only fear i have is how quick they can be to shut a page down,and how slow to react to feedback.
I intend on setting one up for our royal jelly and honey.just a case of finding the time.
