To re-frame the above as completely positive:
I suggest that a "new user survey" be conducted.
That new users to Picard are offered entry into a "user experience survey".
And that this offer is shut down after 35 new users join the survey.
These new users are then asked the 1st batch of questions such as;
What are your expectations of Picard?,
How have you prepared to begin to use Picard?,
What is your desired outcome (from using Picard)?,
Do you know where to get assistance with using Picard?
One week later the 2nd batch of questions is asked:
How are you going with using Picard?
What is working well/making sense/intuitive?
What is not working well/not making sense/counter-intuitive?
Results gathered are then fed-back into user training/UI design of Picard.
Then similar survey of new MusicBrainz contributors.
With again results being fed-back into user training/UI design.
(Though surveying MusicBrainz first and then Picard second would have the advantage of preventing a wave of enthusiastic, low IT-skilled Picard users attempting, and failing to suceed on MusicBrainz. From this point of view a wave of successful low IT-tech-skilled converts does seem much valuable than earlier wider successful-uptake of Picard.)
I'd be interested in being part of such a project.
