`  == Edits ==  I just did (another) major re-do on this article.  It suffers from ``edit creep.``  I don't know who removed all the citations that were in here, but please don't do it again.  Remember WP:Cite Sources.    The article also lost some worldwide refs, resulting in a very USA-centric version, I tried to restort a little bit of info on other nations, I encourage editors from outside the USA to add more info, perhaps here on the talk page, or CAREFULLY into the article itself.  But please, no links to your farm, OK?  ;-)  It's very frustrating how many people put in commercial farm links, but that said, some commercial groups also have some good articles and useful information, that, while not entirely neutral and not always well-sourced, also does not appear to be available elsewhere on the web. So, when the information is accurate, please do not remove it just because the link is somewhat commercial unless you can point to a violation of wikipedia policy (such as, no link farms, no links to paid content, etc.)  When you can replace a footnote with a more neutral source, that's fine.  I also get the feeling that there are more controversies out there. When you edit, please be fair to ALL groups, WP:NPOV is a pillar of wikipedia, after all.  Thanks.  `
