It's really hard to know what a "steady stream" is without useful quantification. I mean to you or me a steady stream might be 100 people a day. Or a million. It's hard to say. (And clearly that would be useful knowledge in the context of evaluating the value of the site.)

On the other hand, if I was getting a million users per day, I'd probably figure out who would care about that audience, and sell to them directly.
