Daring Fireball, Talking Points Memo, Technologizer, and Macworld recently posted some information about what operating systems and browsers their readers are using. Here's the report for kottke.org.
OS statistics
| OS | Now | 6 mo | 1 yr | 1.5 yr | 2 yr | 2.5 yr | All-time |
| Windows | 54.1% | 56.5% | 63.4% | 63.3% | 65.6% | 70.1% | 62.5% |
| Mac | 40.2% | 38.2% | 31.7% | 32.2% | 29.9% | 27.2% | 32.9% |
| Linux | 2.5% | 2.9% | 3.2% | 3.4% | 4.2% | 2.4% | 3.1% |
| iPhone | 2.3% | 1.6% | 1.2% | 0.6% | - | - | 0.9% |
The general trends are obvious here. Mac usage among kottke.org readers has risen -- over the past year in particular -- while Windows usage has fallen by the same amount. Forty percent of all kottke.org readers now use a Mac.
The adoption rate of Snow Leopard (OS X 10.6) by kottke.org readers is less than that of Daring Fireball readers. Of Mac users who visit kottke.org, 47.4% are on 10.5, 34.4% are on 10.6, 8.1% on 10.4, 4.0% on 10.4 (PPC) and 3.7% on 10.5 (PPC). Among Windows visitors, 61.9% are still using XP compared to 32.6% on Vista.
Browser statistics
| Browser | Now | 6 mo | 1 yr | 1.5 yr | 2 yr | 2.5 yr | All-time |
| Firefox | 44.6% | 46.1% | 50.4% | 48.9% | 47.0% | 50.1% | 47.9% |
| Safari | 27.9% | 25.4% | 17.3% | 17.7% | 15.9% | 13.7% | 19.1% |
| IE | 18.5% | 21.3% | 25.9% | 28.7% | 31.1% | 32.2% | 27.0% |
| Chrome | 5.6% | 3.7% | 2.8% | - | - | - | 1.8% |
The numbers for Firefox and IE are falling while Safari and Chrome usage are surging. The Safari nummbers are surprising to me...Safari is not a new browser but its usage by kottke.org readers has increased by more than 60% in the past year. I predict Chrome will surge in the next 12 months to overtake IE.
Two miscellaneous things
1. Google is ruling the search space more than ever. 93.2% of the incoming search traffic to kottke.org comes from Google. That's up from 91.2% a year ago and 83.7% two years ago (!!). Bing is second with 3.4% (MSN and Live combined for 5% two years ago) and Yahoo is a very sad third at 1.5% (they were at 6.9% two years ago).
2. Twitter now accounts for 2.9% of all traffic to kottke.org while Facebook is 0.9%. That's understandable considering I invest a lot of time on Twitter and almost none on Facebook. For reference, StumbleUpon is at 6.5% and incoming Google search traffic is 25.5%.
