I use Google Analytics to track this website's performance, and especially to get some insight into usage patterns and (anonymized aggregate) demographic data. Here's a quick look at the reports for the last month. I grabbed a few snapshots of total users, gender and age demographics, and location data by country. There are no great surprises: traffic is healthy (although this is by no means the best month so far this year - one month had over 450K unique active users), the percentage of female visitors is still terrible low - far too low - and the US is by far the largest single country of origin. That last item is interesting - the amount of non-US traffic has increased a lot across the board over the last couple of years, and while the US traffic has increased in terms of raw numbers, it has decreased by about 15% in terms of percentage share. In other words, there's lots of new traffic coming in from other countries.
