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
