Another Russ entirely, MIT and Plan 9 guy Russ Cox, has a blog new since January. His latest sees Plan 9 services supporting legacy systems with great backups on SHA1 hashes in the form of venti(8), an archival storage server with which Cox is intimately familiar.

Trying to think of the simplest useful example I could of stringing together nifty Plan 9 features without writing any code. Simple as it gets: using the archival file system to present a browseable cache of the past of a living web site under active development.
