It hit 'singularity' (everything came down to a graph edge; the system is comprised of nothing else) in 2005. I've had some great advisors and the feedback is consistent, “That it’s unique is not interesting if it's not compelling. Show how it’s compelling.” So I’ve stumbled with my limited resources over the years to do that and I’ve come up with a database, of all things, but it’s actually the "programming language" masquerading as a database.
I'm thinking of offering it as a service and if you want to see where that's going, it's at http://www.kayadb.com (although it’s not meant to be looked at yet). I'll do a Tell HN when in a few weeks when it's closer to being ready to show.
