Re: Why not just accept micropayments
This is where traditional payment methods fall down in my view. Too expensive to process most transactions for anything less than a few dollars/pounds/etc. (Unless you're paying in Zimbabwe dollars, then you never have enough zeros between the significant digits and the decimal point.)
This could be Bitcoin's niche, maybe. Then there's the thorny issue of taxation. GST in Australia for example is 10%, is it worth bothering to declare 10% of 5 cents from some anonymous viewer? (You could probably declare it as a lump sum, but then some anal retentive will want to know the detail — I guess they can have it too.)
