For one, just indices in a strongly consistent distributed store, with ACID, is a big deal. Doing this yourself with another strongly consistent DB is a massive error prone PITA.
Plenty useful -- we have SQL-like query tools at work (which operate on SSTables and ColumnIO) that I use extensively nearly everyday and I almost never do a join. Just SELECT and WHERE gets the job done 98% of the time for me.

I can see many of the exploratory data analytic can be done without joins. Well, my experience could be too specific though.
Right now, I'm most interested in seeing RethinkDB see more traction... it seems to have most of the features I look for, and I, for one don't mind more programmatic queries, and the management interface is really second to none at this point... MS-SQL, I'd probably consider a close second.
