One would be to have the extension openly available, and wait for people to install it and send us their reports. This has the problem that it would give us results from a very narrow kind of people, who are already technical experts. We do not need hundreds of participants as much as we need that they are representative of typical intermediate users. For instance, Nielsen recommends testing with 20 users when collecting quantitative usability metrics: http://www.useit.com/alertbox/quantitative_testing.html So, the other option would be to develop this extension, and then have some GNOMErs recruit participants (e.g. friends, relatives) and set up the experiment for them. I guess that it should not be hard to recruit a couple dozen people this way. The experiment itself would need to be as automated as possible, so one of us could simply go to our friend's computer, download and install the extension, and upload the results a couple of weeks later (together with some general demographic info on the participant). We can discuss if it would make sense to make the data publicly available (after anonimizing, of course), or if only some selected people should have access to it. As for the technical part, I don't really know much about the detailed implementation of the Shell and how we could write this experimental extension (maybe it could be built on top of the a11y infrastructure???).
