1. Put a fixed price - better from the seller's perspective because even if your clients are not making any income you still get your subscriptions but might scare people off, especially those that want to try out the service.
2. Take a percent of each sale generated through my platform - better for small clients since they don't lose any money if there are no sales but might scare off some that generate a lot of sales and start to think that they lose too much this way.
Both have advantages and disadvantages, as clients on other services...what would you prefer?
I honestly rarely hear about RSS. My idea is to build whatever users are asking and stop investing time in features that will go unnoticed but, since this is a young project, I might be wrong and losing something.
My question towards this community is...how many of you still use RSS to subscribe to content?
