I see it more as a move from "one size fits all" to more specialized tools. The term "nosql" is pretty useless as it's way too general. Both your comments about "not implementing the hard stuff", and GP's about schema, only applies to some of the "nosql" projects.

Instead of looking at it as "aaawwm! NoSQL is attacking our bellowed RDBMS", try looking at the different projects and what they bring to the table. Maybe some of them can be a useful addition to your systems.
