The problem is we don’t have good language. When I’m on Flickr I’m a photographer or a commenter. When I’m here I’m a writer or a blogger. When I’m on Craig’s List I’m a job seeker or a buyer or a seller. When I’m on MSN Search or Google I’m a “searcher.” When I’m on Memeorandum I’m a “reader.”
“User” just seems so unsatisfying. “Participant” is a lot closer. What do you think?
