Hey, Ben! Can you make an " everything you need to know about Raspberry Pi "? 
For anyone who is after a printed 'book' rather than a website of Forum, there is always the excellent "Raspberry Pi User Guide" by Eben Upton and Gareth Halfacree which is now in its third edition, having been updated in September 2014 to include the model B+.
It is the bestseller on Amazon (U.K) in the 'Computer Architecture & Microprocessors' section, so they must be doing something right... or isn't this the sort of thing the OP was looking for?
