Hard to understand edit

People unfamiliar with the subject matter will find it hard to understand this article. See for example the first paragraph. Sentences don't link together, unmentioned things are implied known, and what does "wd" mean? Someone knowing of the topic should rewrite, and I suppose the grammar should be improved too, and possibly this article should be longer. — Preceding unsigned comment added by 77.247.145.184 (talk) 19:26, 25 January 2013 (UTC)Reply

Much easier: I simply undid the January 11 edit, which looks more like a mistake than vandalism - it replaced a paragraph and a half with "wd". --Vaughan Pratt (talk) 03:08, 30 January 2013 (UTC)Reply
