Interesting – I wonder what the variance in the “kind” of sign-up might be. Perhaps those designs that highlight the “free” aspects will encourage a lot of try-outs that then bail after the 30 days; while the designs that don’t will see more longer term sign-ups. The results of a follow-up after 30 days to see how many stay could also be enlightening.
