Starting in Chapter 3 we are going to have exercises at the end of each chapter. I'm curious if it would be a good idea to have a wiki for these exercises? It might be a good idea to have a place to keep the knowledge as we figure things out.
For example a Chapter 3 exercise is getting Postgres db installed on your machine. Part of me thinks it would be a good idea to have the steps to get that installed saved off to a wiki in a kind of FAQ, but I'm also of the opinion that giving the information away like that hurts people from learning by doing it themselves.
So, what are the thoughts on having a wiki type place to answer the exercises?
And if we do want to have a place to keep our knowledge, what and where should it be?
