I think Amir is right, but it's really beyond the remit of LangCom to fix some of those problems.
However, if this wiki were moved back into Incubator, and had to re-propose itself via LangCom, then this committee could use its expertise to evaluate its use of language, the sufficiency of its community and translation efforts, etc. It clearly fails your minimum criteria as it stands, and fixing it requires more than just deleting bad content.
