Problematic articles
Maybe "baseline quality" can mean: complies (to the best of our knowledge) with NPOV, V, and NOR; if an academic topic perhaps draws on a certain minimum number of sources, or we can have a checklist - identifies major debates, identifies key historical moments?
One thing I am starting to think is, how can the Wikiprojects be of use? Well, one criteria for baseline quality could be: to give the relevant wikiproject a foothold or foundation for taking it to the next step. This would involve in effect giving wikiprojects assignments. But I think it is perfectly reasonable, for example, to ask Wikiproject to develop a bibliography of works published by major university presses or in the leading journals in the past five years. Just having such a bibloigraphy would help us know how complete the article is, and provide future editors with something "to do" (i.e. start reading through that bibliography to add to the article). This would not be a full-scale "good article" or "featured article" drive, it would be something short of it - but still something, something we have been lacking (a systematic algorithm of stages through which to move an article, with "to do" lists at critical moments e.g. first develop a bibliopgraphy; then review the literature; then revisit NPOV issues.
Just an idea.
