I had trouble following your message. You've stated that Kdb+ looks good on a resume, Haskell requires explanation, and IP is bad? I'm not a big fan of closed source myself (and Kx Systems sounds like it would have a lot of red tape), but the technology is supposedly very fast and I find the language to be very simple and charming. I'd love for our analytics database to migrate , but I think the technology would really confuse our IT folks and it would be difficult to describe why it would make our jobs easier.
