While we can't give exact numbers for all of our readers (many read but don't register at all), I was able to extract the information from the database, based on registered users who informed their country of origin (which is an optional piece of information).
The top numbers are:
New Zealand: 23%
Others are not representative, although I am pretty much confident all countries are represented in the database.
Yes, the ratio for visitors is what I've posted in the previous post (after the chart's post). I've been following the logs for a while (I have almost 100GB of logs here to play with) and the referers are mostly google.com, news.google.com, yahoo.com, gizmodo.com, engadget.com, pocketpcthoughts.com and other sites related to Pocket PC.
Interesting enough MSN Search is not a big presence...
I stopped doing the full logs - running loganaliser for 2005 alone takes a few hours on a dedicated machine. I am now doing it per year instead of the full thing, and archiving each year. So now I started doing 2006 alone...
