Not that I do ~~much~~ anything with NoSQL, but I really enjoyed this article about Oracle's NoSQL Database, especially the point where they removed the white paper, titled "Debunking the NoSQL Hype" (from May 2011!).

Another favourite:

  As a result, NoSQL databases may only have partial or no sql support.

No shit, Sherlock! :-)
