I think it's worth $50.
My question is what are the best resources on this topic?
I suppose i need 2.5 as many times the members at the $20 rate to make generate the same revenue. I've got 100 users @ $50, but will I get 250 @ $20 ? If I did get 250 at $20, the revenue hasn't gone up.
$50 seems like the better plan to me. Ofcourse, if I ask the users who haven't subscribed and still use the free model, they think $50 is too much and they would be more likely to pay $20.
I'm sure there's lots of discussion on this topic out there, but as soon as you type in "membership subscription" at google you get garbage like pay pal and netflix, and not any nerdy discussion on the topic.
