I posted an answer to a Question about engagement on the site, that was actually intended to be just a comment but grew while I was writing it. Even though I truly mean what I wrote down there, I was not really happy with my answer, for a very simple reason. I felt it was (even it was not meant to be that way) rather a criticism and lacking of any suggestion. So I further though about the question "how could a collaborative spirit be introduced practically?" and I came up with this idea:
How would it be to introduce something like a collaboration
tag
on the site?
Gaining for questions like:
I'm working on an educational Open Source Score Repository for progressive exercises from the very beginning onwards to more advanced studies for the Violoncello. Is there anyone interested to take part, contribute or suggest anything to this project?
I know this suggestion is gonna raise major problems with the site's policy. Still I would like to throw it in.
