Great work on tutorials. Could this mean PRs to the dev portal are being accepted now?

Developer's reference is really good as well. I hadn't realized until now how often I'm actually digging through the source code as a reference instead of referring to the documentation.

I think one tutorial that is really missing here is a high-level for creating your own language binding for json-rpc. I'm sure there are some devs out there that would love to traverse transactions with R.
