Please stop being a miserable delete artist I note that almost all of your edits are to destroy somebody else s well meant contributions Certainly we need to keep rubbish of the Wikipedia but we do not need self appointed self righteous policemen picking at details That behaviour poisonous Wikipedia It is hard to encourage new editors to contribute when you just beat them up over pedantic nonsense In my case you attacked a non controversial contribution to an article because of references Not because you disagreed with it or even understood it Just because of the legalistic issue of references And the article does actually read a bit like a company sales promotion but you would not have noticed that more serious issue Well I ll tell you a dirty little secret about Wikipedia Lots of good contributions do not have references Particularly about maths science and technology But just because some well meaning editor does not go to the extra effort cite does not make it original research If there is controversy then certainly references are essential and need to be good ones But most of the world is not controversial Just look at your User Contribution history What a miserable tale it tells So if you must edit wikipedia please try to contribute positively rather than just focusing on picking on other people s generous contributions
