At first, I thought that the guy was using KS as an exit strategy from his current startup, Maptimize. Then I realized that he was creating a new, open-source JS client-side library, which is a real need. Kudos to that!

What strikes me is how one could use KS to "sell" useful code/assets from a failed startup. Or, to an extend, use KS as an exit strategy - going open source instead of going public.
