I think ##hubski would have worked, but I agree that getting #hubski is a good thing.

mk, forwardslash we may be able to get #hubski on freenode by appealing to the Freenode staff. I've been talking with thundara and it comes down to this: since Freenode is technically aimed at FOSS projects, the appeal may be helped by either

a) making the site itself open source -or- b) leveraging hubski support of arc / being built on the same codebase as hackernews
