The two main arguments for why these articles should not be deleted are:<p>1) The languages exist, are supported, and are used by many users<p>2) There are other bad articles on wikipedia<p>Both of these are, unfortunately, terrible arguments.<p>In response to the first argument:<p>Wikipedia's rules state that for an article to exist, it must be proven notable by certain types of accepted references. That does not include tutorials, blog posts, software's official website, or questions on support websites/forums. These rules are unfortunate, and have been sources of much arguing, but they still stand.<p>We, as programmers, get upset when information that is useful to us is removed. The rules exist for a reason, though; one place where they are often enforced is the addition of video game articles. There are hundreds of thousands of video games with significant user bases. Wikipedia has made it a point that it does not intend to be a catalog of software that exists, and for that reason video game articles are deleted often. In order for software to legitimately qualify for an article, it must be significantly, demonstrably important. Existence and popularity is not enough.<p>In response to the second type of argument: existence of violations does not justify other violations. If don't think the blue slime from Dragon Warrior deserves its own wikipedia page, mark it for deletion and argue your point, but don't reference it as why your bad article with weak references should remain.<p>Wikipedia has a LOT of articles that are against its rules. We have become used to these, and depend on them, so we get upset when the rules are enforced. Have a look at the actual rules and I'll bet you can identify plenty of articles you have read that are in violation:<p><a href="http://en.wikipedia.org/wiki/Wikipedia:Notability" rel="nofollow">http://en.wikipedia.org/wiki/Wikipedia:Notability</a><p><a href="http://en.wikipedia.org/wiki/Wikipedia:No_original_research" rel="nofollow">http://en.wikipedia.org/wiki/Wikipedia:No_original_research</a><p><a href="http://en.wikipedia.org/wiki/Wikipedia:What_Wikipedia_is_not" rel="nofollow">http://en.wikipedia.org/wiki/Wikipedia:What_Wikipedia_is_not</a>
