I also think it's very important the users are not treated as consumers. We
already want to take part and help the project. The worst thing to do is to
ignore reported issues. It would be a million times better even to just say
"No, this will not be fixed because of ..."
Trisquel's development as a whole should be made as transparent as possible.
That way everybody can see who's doing the work and join in, if they have the
skills. I would think quite a few free software hackers have their eyes on
Trisquel. Such a time bank scheme would be at least an interesting
experiment. On the other hand sometimes such external rewards have been
reported to act as disincentive, like when a children were rewarded for
playing they ended up playing less.
These are things that must be addressed to make Trisquel as resilient,
democratic and good as possible.
