Tagging for NOSI?

I was wondering how people in the NOSI community could tag their bookmarks on del.icio.us or ma.gnolia (or other bookmarking systems) and their blogs and such, in a way that we could easily find it. Should we have a 'nosi' tag? Or use a tag combination, such as 'nptech' and 'floss' or 'oss'? Suggestions?
