Eric’s model is very close to the trend in which the visitors to my site are doing. A large portion of them are still using IE but there is an uptick in Firefox users.

Maybe it doesn’t pick up the data correctly from version to the next and there’s a slight blip.

I found the heat graph interesting.

I assume this is en-US data? Since other people have different holidays I’d be curious to see if that matches other locales. Also can you please avoid terms like Spring and Fall, they mean nothing to someone from the Southern Hemisphere.

Very interesting!

I’m curious though, that is the Y-axis in that graph? Active Daily Users?

I’m also baffled as to why Firefox usage goes down around Firefox releases – wouldn’t you expect the opposite?

If you really want to illustrate the similarity between prediction and reality, show the difference between them as a percentage error…

Also, as an analogy with stock markets, be careful with month-to-month growth. Try with the same month last year instead.
