I recently read a post about the platform stats of Cornerstone (the Mac SVN client). They broke down like this (about 5 weeks after Snow Leopard had shipped):

• Mac OS X 10.4 Tiger 4.7%
• Mac OS X 10.5 Leopard 86.8%
• Mac OS X 10.6 Snow Leopard 8.5%

They can do this analysis, probably, because they have the registration system built into the app, which can transmit the platform version info to them. We can’t do that with Tap.Tools because there is no network exchange when you authorize your software. However, we can get some statistics about the readers of this blog. They look like this:

• 35.8% – Safari Mac
• 25.2% – Firefox Mac
• 17.3% – Firefox Win
• 14.7% – IE Win
• 2.27% – Chrome Win
• 1.1% – Firefox Linux

So it’s about a 60/39/1 readership on Mac/Windows/Linux. That’s roughly what I would have guessed. I am a little surprised how many mac users are using Firefox though — that’s a pretty strong number.
