we tried yearly pricing and it turned out to be a big pain.. people forgot about their subscriptions and we're confused/angry when it renewed, people's credit card numbers changed or expired after a year and caused subscriptions to expire, etc etc... $10/yr pricing on a monthly subscription doesn't work because there are just too many fees. Appreciate the feedback though... still trying to figure out the right price.
Which fees? If you mean credit card processing fees, then even $20 would make more sense, no? You have to remember: your service isn't twitter so I think people would be less inclined to pay a total of $5-10/month. (I don't know this market well enough, but that's my initial takeaway.)
