What about if it isn't OSS? Do you like more reference style docs (i.e. this method takes arguments x, y, z, returns a string) or narrative (i.e. to accomplish goal x, you'll need to do y and z like this ...)?
Maybe a couple of different example applications to serve different goals would be helpful as well instead of one monolithic project.
I've just never really been big on blog posts that are showing me code and why things are there, when that can all be done within the project itself and I can run it, maybe setup breakpoints and hack around. I can get up and running faster that way, and I hate high barriers to entry when I'm looking to play around with something.
