So I toke a sample of data from my sales list from last year. As the REALbasic users buying plug-ins are the more professional ones, I think this shows more the professional than the hobbyist users. But I think the sample is big enough to show the spread worldwide. But in general it looks like the spread follows knowledge/income rules. Only people with enough knowledge about programming and enough money to spend it on my plug-ins are visible on this map. I hope the resolution is low enough to keep people's privacy.
