I've been fixing bugs and working on some smalls thing with it, mainly in figuring out what's involved in adding a MOP to get the mostly-native performance that I need, but with with the dynamicism that I'm used to having. I just released a new bootstrap last night and will be doing an update to the website tonight or tomorrow to reflect some of the changes in things. (Tesla is now the recommended compiler over the old one written in Objective C.)
Once some of that is worked out, I'd expect to see something more being done on Cubik, as until then, there isn't much use.
FOAF updates: Trust rankings are now exported, making the data available to other users and websites. An external FOAF URI has been added, allowing users to link to an additional FOAF file.
