Seriously, if anybody is interested in working on Usenet filtering and general architecture of the next - semantic - layer of the Net, in any capacity, from helpfile proofreading to idea input to UI coding, please read the Newsfilter project description, join the mailing list, and anything you can put in will be greatly appreciated!
I am just about to start a new discussion there on the Universal Subject/Feature ontology, so you can be quite in time for that.
