Meta should be about
- meta-project: discussing and formulating project-wide
(i.e. not
language-specific) policies; organizing events,
contests
etc.
- meta-content: organizing and preparing content, e.g.
templates; language
files
- meta-code: coordinating the development process - bugs,
features etc.
If the meta-wikipedia got rid of mess, I don't have any
reason to hesitate to use meta for development of wiki
software.
