You may remember my post from a few days ago about making custom maps using TileMill. Purely for entertainment value, I took a look at my analytics logs from the day the post was a hit on both Hacker News and Reddit, to see how they and their users differ.
Can you provide any details of browser usage between the 2 sites? My guess is HN has more Firefox (as it's open source and hacker-friendly) and proggit has more mobile.
Thanks. As a web developer working on sites that see IE usage averaging around 60%, I can't imagine how much more rewarding it is seeing IE at just 2%.
