I've given serious consideration to offering a class.  Something where businesses that are considering blockchain technology or bitcoin itself could hire me to come in and explain the technical details to their staff.

However, I'm much better in a Q&A format than I am at organizing multiple concepts into a cohesive book.  I'll give it some consideration though.

In the meantime, if you have additional technical questions about bitcoin, you should post them here at bitcointalk.  There are other members here that do a great job of answering (such as Achow101 and HCP).  Feel free to send me a PM to point out the post with your question so I don't overlook it.
