A homepage for multiple projects
I'm working on a several projects with a common theme where the main branch and release usually done by the user which started the project.
This has the effect that each of the projects usually publish a different URL for its users as the 'main site', with username as part of the URL.
I would like to create a minisite around the common theme (think neuroscience.bitbucket.org), which will contain some content I'll be able to control and links to the documentation, download pages and issue trackers of the actual projects. A sample site which is my inspiration is http://neuralensemble.org (but there they have a dedicated server which I would like to avoid).
This has many advantages: Projects benefit from the good reputation of other projects, exposing the users of one projects to all others Single URL = more search engine visibility, higher page rank * A URL without a username is more respectful, easier to remember and does not depend on change of personnel which is common in open-source projects
No need to unify the issue tracking or release mechanism, as development may still be done in a distributed manner by many different users.
Note that having some mechanisms would cause me to unify all projects on bitbucket, while currently some of them are on github. :)
