Have you found any interesting personal projects to use Q/Kdb for? I've been trying to learn it for years but haven't found anything to use it for that really makes me want to learn.
I am currently working on something which is roughly a "knowledge/document/media relation" database based upon treating Michel Foucaults "Archeology of Knowledge" as a specification for software. If it's workable and interesting I will get a domain for it and show it off, if not it's a good project to learn on.
