Having written my own naive Clojure dot product, I can definitely appreciate what you guys have done!

Any plans to attack sparse vectors? Performance on the sparse vector operations I wrote was poor, but being new to Clojure it wasn't a great implementation.

We have sparse vector code built on hiphip that's slated for open-source release down the road (once we get the resources to polish it) -- stay tuned!

vectorz-clj has sparse vector support.... it's bit of an hidden feature at the moment (you'll have to use Java interop to instantiate a SparseIndexedVector) but it works and is pretty fast for many operations.
