Hooo boy, we wish we could. Sales, much to my own inner-hacker's chagrin, is something done best by building relationships in person. You can put some of it off to a nice self-serve web experience a la Adsense, but if you ever want to make the big bucks (enterprise fuck-you bucks) you have to have sales people talking to real people who can write big checks and aren't Googling for self-serve solutions to their equally big problems.

Computers can't write sales copy or do a great in-person pitch yet.

You can, but the margins are much, much lower.
