I think part of this can be attributed to the ease of reading source code in the golang source tree. Mostly every part of the go tools are written in golang sans some architecture specific code. Most of it is well documented and if it isn't, it's generally straightforward to follow. Also, the recent addition to GitHub PRs proxying for Gerrit CRs is really nice.
