Around the summer of ‘09 we saw a distinct rise in the number of companies and startups that were building products which utilize the Facebook social graph. Facebook Connect became a distinct trend as more and more sites such as Thread and The Huffington Post began using this technology for both integral and ancillary purposes.

Google Analytics Browser and OS Stats

The key takeaways are:

1. Firefox on Mac and Windows accounts for over 50%.
2. 45% of our visitors use Windows. 38% use Macs.
3. One in five users is browsing with IE.

This is significantly different from global OS and browser usage. According to Net Applications’ operating system market share, global Mac share is under 10%. And the same source tells us that IE has 68% of global market share, with Firefox at 21%.

Our visitors are particularly savvy users, as indicated by the widespread adoption of Firefox. I would wager that many of them are creative professionals, as indicated by the unusually high Mac percentage.
