'It seems to be against Gmail's terms of service to open an account soley in order to create a media commons. Too bad, as Gmail's very generous storage would make for an idea spot to swap music, video, and other media back and forth amongst a small community. Maybe there's a better way to do this, and a more legal way, but... Gmail sure does make itself convenient. So you wouldn't, for instance want to tell a bunch of collaborators the username and password for a dummy Gmail account, because that is most probably against the terms of service. So this is certainly to suggest that I would never encourage any such activity or participate in anything illegal myself, even if I might be inclined to agree with those that say "Google would never know or care, would they?".'
Well, I don't know about all that. But I overhear some good stuff sometimes.
Someone else's take on the many uses of Gmail, here. It's enough to make a guy want to experiment.
Reading: lots and lots of book reviews.
