I made a calculation:
Everyone knows that 1% of a population consist of extreme people. This
means that 2800 freaks can be found in Iceland. Do you really find it
unlikely that 70 of these 2800 will be willing to learn háfrónska
before 2010. I find this a realistic estimate.
500 speakers before 2025, I'm certain of that. Háfrónska is an
honest language, it makes no concessions
