Sure, but perhaps companies in the middle, with less than 50 employees, might be willing to spend some money, but not $50 a year per employee. Say, a 10 employee company - that's 500$ a year, which isn't huge, but not peanuts either. If Google could get 200$ out of them, and still make a profit, it seems like a win for everyone. No idea what their actual costs are, but they can't be that high if the advertising is anywhere close to covering them.
Yikes, I thought it was 0-50 for free and any users past that were $50. So 51 users would be $50/yr. I guess you really have to justify that 51st employee :).
Also the color, layout and stock photos on the 'how it works' page made me think of one of those pyramid scheme sites.
