I described this site to a friend as "the best place I know to spend time constructively when you should be working". But it occurred to me that I don't know the exact way to describe what we're doing. Mark Twain said "work is whatever a body is obliged to do, and play is whatever a body is not obliged to do", but we're not exactly playing. On the other hand, I wouldn't (unless desperate for something to put on my CV), call it voluntary work. Is there a word or short phrase for what you're doing at this moment?
AFAIC, this question was perfectly positioned in English.stackexchange. It is not a discussion about the "behaviour" on the site, but a question about a word that can be used to describe the activity of the participants of the site. Hence, it is a question about language use and vocabulary.
I feel it should be moved back.
