I understand that you would a constant flow of cash to keep something like this running but I am someone who enjoys a "pay once and forget about it" system. I rather pay a one time fee of say $30 to get rid of banners, get access to mobile app and while still being limited to say 200 MB or something. Yes this is lower than the yearly fee but you also might get a lot more people interested in paying where they might of not before.
