He engages with his fan base a lot. So yeah, there are lots of jokes and things like that. It's fun to get involved with everything, but you don't need to in order to just enjoy his books.
By the way, most people suggest starting with the Mistborn series. "The Final Empire" is the first book, and it's really fun. A good introduction to Sanderson. They're still big books, but not quite the commitment of "The Way of Kings," which is the first Stormlight book. Whatever you start with, I hope you enjoy it!!
