....Why don't I just bill the user via email using something like PayPal? Think about it, the user enters their email and phone number on their phone, promises to pay the 99 cents when they get to a real computer and that's it. Done. No middle man, no carriers, no aggregators, no e-wallets, nothing. Just an old fashioned billing system....there will be lots of people who will never pay. Fine....Some will gladly pony up for the convenience, others will try to ditch the cost because they're like that.... If they lie about their email or SMS, then they don't actually receive the answer.... Bill My Email. Quick, easy and simple.  via [Russell Beattie Notebook]

Not the first really good idea from Russell.
