I think that much of what has been expressed is interesting.
I am particularly interested in the idea of "marking" stacks,
so that people can make decisions about the amount of work
involved.
I think that the Python has a good method of doing this with
the Cheese Shop (
pypi.python.org), where
packages are marked with tags 1-7, representing planning to
mature + inactive. They additionally have tags for other
reasons, such as platform, purpose, and category. A full list
can be viewed at
http://pypi.python.org/pypi?%3Aaction=list_classifiers
Maybe this is something that we can add to the manifest,
which can be in turn added to the wiki?
