We’ve had over 5,000 users submit data from the Test Pilot tabs study!

Considering that people had to first hear about Test Pilot, then opt in by installing the extension, then opt in again by choosing to submit the data, 5,000 is a really good number. Better than we had any right to expect, certainly.

Over the past couple weeks, I’ve been sifting and analyzing the data, and working with Blake Cutler from the Mozilla Metrics team to generate graphs of interesting statistics about tab usage. I’ve just put up a results page showcasing several of these graphs.

We’ve also posted samples of the aggregated data which are free for anyone to download and use. There was some discussion on my previous post about how to aggregate the data in a way that was still useful to researchers. What we ended up doing was building files that include row-level data from a random subsample of the users that fit particular criteria. It’s stripped of any information on the language/locale, operating system, or installed extensions for any individual user in the sample.

Third-party researchers have already begun using the data to do their own analysis! Andy at Surfmind.com has a post containing some very cool-looking visualizations and has proposed an interesting theory about there being two classes of heavy tab users.
