By the way, no one so far has questioned the results of the UX test
being based on responses of 7 (seven) people. Where do these people

the margin of error and will the results repeat with a larger group?
The exact composition of who you ask to participate in a study is indeed
important, but while it would be great to have a more geographically
diverse sample, sometimes you'll have to settle for what you can
realistically get hold of.
I'm really happy that there is usability testing being done in the first
place. I personally felt discouraged from making any kind of usability
testing in the past, mostly because I didn't have a usability test lab
set up at home, with a two-way-mirror and all the necessary equipment.
As a result, I ended up doing no usability testing at all. :(
Jakob Nielsen recommends around 5 people, because in his experience,
you'll just keep seeing the same things over and over after that, and 5
easily catches the most obvious errors.
That said, the test should be able to be repeated by pretty much anyone,
with new participants.
5 — now that is your crazy uncle kind of person that...
Eh, so these are people who volunteered their precious time in the hope
to make a project better, and as a community we should be grateful for
As part of the introduction they were promised that it was the software
that was tested, not them.
I would become extremely hurt if I tried to help make software better,
just to have the project call me a crazy uncle afterwards.
