Often times Ubuntu teams need to collaborate on team scripts/webpages/artwork/documentation. Because Launchpad does not currently allow teams to have non-project branches teams either create placeholder projects of no use other than to hold branches or just use personal branches. The list of Ubuntu-related projects will (and has already started to, IMO) become loaded with cruft. Ppersonal branches are not very helpful for team collaboration because it mean team members have to track every other team members branches and there is no "canonical" branch which is important for many tasks.
My use case:
I'm writing a python script to create task lists and information pages for the MOTU SRU (~motu-sru LP team) team. All team members should have access to working on the script and the script may be automatically synced to the qa.ubuntuwire.com (MOTU team server) for hosting so we need a canonical source.
My current solutions:
I can either use my own +junk branch or I can possibly use ubuntu-dev-tools project, even though this script is not a part of that project, because it is just the closest project available.
Well, I can see the point. But I think the thinking is that something like the script you're talking about writing is something that you might want to file bugs about say, and then you'd want a project.
I guess the part that I don't get is that I don't really see why having lots of small ubuntu related projects is a problem.
