David,

I do understand where you are coming from. With open source software the
line between user and developer is very grey. Also open source software
tends to get pulled by people in many directions, by people with specific
needs. For example, one committer may be hard at work working on map reduce
over secondary indexes and may only be tangentially aware of another feature
like pluggable row cache.  This is true in any large project. Only someone
who can dedicate substantial time to an open source project can really have
their finger on it's pulse.

I noticed you mentioned "with out all the noise". Well noise is in the eye
of the beholder. Too much information for you on secondary indexes and
hadoop might be non enough info for me. Not to say that the information
dissemination system could not be better but...

I would say that Jonathon's "State of Cassandra Talk"
http://www.datastax.com/wp-content/uploads/2011/07/Keynote_CassandraSF2011.pdfis
a solid look at where Cassandra is going in the near-mid term. I

Edward
