I would take the "would you use this service" feedback with a grain of salt. It costs you nothing to say "yes", but everything changes as soon as you start to charge for it. Going from Free to $0.01 for any online product or service significantly changes your conversion numbers. You might get better feedback standing on a corner downtown, asking if people would use your service... and charge them $1 for a voucher that would allow them to use it when it is ready. PS: Please get out of stealth mode!
