as far as i know too many entries in wikipedia are rated as start class see e g the entries on michael albert murray bookchin and lots of others but i've never seen such massive editing usually for copy editing to be done in good faith and not as an excuse to interfere with the content it should be done on a piecemeal basis a sentence at a time so that objective readers can assess it the fact that nobody can assess spylab's massive editing unless one is prepared to spend as many hours of work as the ones he spent on this easily creates a suspicion that his motives are far from innocent
