I worked at OkCupid for a bit and got to see OKWS in its full glory. Though it sounds kinda daunting from the documentation, it's actually reasonably workable.

I worked at OkCupid for a bit and got to see OKWS in its full glory. Though it sounds kinda daunting from the documentation, it's actually reasonably workable. I was able to get a rough app up that talked to a bunch of different internal services via async RPCs within my first couple days (the first compile took forever, though...). One of the coolest parts of the stack was that every function call you made was non-blocking unless you wrapped it with BLOCK{...}, and within a BLOCK code that was written sequentially got turned into callback-based async calls behind the scenes. The other cool part of the stack was getting core dumps on segfaults. Heh.
