Deletion of Farseer Physics Engine

Comment: 1) By "useful", I mean useful for our core readership, high school and college students, who use Wikipedia more than anyone else. They are especially likely to look for articles about software, and we might as well have such, and work to improve it. However, I am not an expert on the topic, so I acknowledge that this can't help very much. (2) By barely notable, I mean that I could not |evaluate the strength of the sources, either in the external links or those discussed above by JulesH and SL93.  I give articles and book sources the benefit of the doubt. (3) I am not wedded to this article, and could care less if it's kept or userfied for now. (4) I searched http://scholar.google.com/scholar?hl=en&q=farseer+physics+engine+3+tutorial&btnG=&as_sdt=1%2C33&as_sdtp= Google scholar for tutorials on this physics engine, and found lots of possible reliable sources. These could be added to beef up the article. Again, I wish I were more of an expert. I am something of a physics autodidact ,and graduated with a Regents diploma from The Bronx High School of Science, but make no claims yet that I am an authority on such

Comment: I wonder how this AfD will be closed with a ,  (released in 2007 = historical), and an unreliable source, a how to video, and books that ''might'' discuss the software. Worst of all, I'm receiving no responses. Some admins do vote counting instead of weighing the arguments

Comment: per |Ignore all rules. This topic is a part of History of computing|computing history. Also, per the article, ..."it is the most comprehensive open source physics engine available for Silverlight." Let's perhaps not be so hasty to delete historical computing topics. Does removal of this stub article actually improve the encyclopedia? Not at all
