I don't like that landing page either. I put it up because people who sell online advised me to and I thought it was worth a test. I'll change it up when I get a chance.
As for charging, check out the looks on the faces of my interviewees who sell instead of giving their stuff away. When I ask them why they charge (even when I ask in an intentionally provocative manner), there's a look of peace on their faces.
The founder of Line2 was on yesterday. His iOS-based phone service has a monthly fee, even though a few phone apps are free. Charging gives him revenues to invest & improve his product + it lets him sleep better at night + it eliminates the freeloaders who take up time and cost a lot to service.
Finally, you know how the guys who switched from blogging to email say that it gives them a more intimate relationship with their audience? Charging multiplies that by 100.
Try it. Seriously.
