maybe this will be of interest. 〈What Programing Language Are the Largest Website Written In?〉 http://xahlee.org/comp/website_lang_popularity.html
--------------------------------- i don't remember how, but today i suddenly got reminded that Facebook is written in PHP. So, on the spur of the moment, i twitted: “Remember folks, the world's largest sites {Facebook, Wikipedia, “Yahoo!”, etc} are written in Pretty Home Page!” and followed with: “To Chinese friends, what's Baido, QQ, Taobao, Sina written in?” Then, this question piqued me, even i tried to not waste my time. But it overpowered me before i resisted, becuase i quickly spend 15 min to write this list (with help of Google): 1 Google ◇ Java 2 Facebook ◇ PHP 3 YouTube ◇ Python 4 Yahoo! ◇ PHP 5 blogger.com ◇ Java 6 baidu.com ◇ C/C++. perl/python/ruby 7 Wikipedia ◇ PHP 8 Windows Live live.com 9 Twitter.com ◇ Scala and Ruby? 10 QQ.com ◇ ? 11 MSN.com ◇ ? 13 LinkedIn ◇ PHP? 15 TaoBao.com ◇ ? 16 sina.com.cn ◇ ? 17 Amazon.com ◇ ? 18 WordPress.com ◇ PHP 22 eBay.com ◇ ? 23 yandex.ru (Russian) ◇ ? 24 Bing ◇ ? 27 Microsoft.com ◇ ? 28 网易 163.com ◇ ? 29 PayPal.com ◇ Java? 31 新浪微博 weibo.com ◇ ? 32 Flickr.com ◇ ? 34 mail.ru ◇ ? 35 Craiglist.org ◇ perl 36 FC2.com ◇ ? 38 Apple.com ◇ Objective J? 39 imdb.com ◇ ? 41 VKontakte.ru ◇ ? 43 搜狐网 sohu.com ◇ ? 44 Ask.com ◇ ? 45 BBC.co.uk ◇ ? 46 tumblr.com ◇ PHP 47 LiveJasmin.com (porn) ◇ ? 48 xvideos.com (porn) ◇ ? … 56 土豆网 Todou.com ◇ ? 81 YouPorn.com ◇ ? StumbleUpon.com ◇ PHP, Perl, C++ … the numbers is site ranking, from alexa.com. (missing ones are mostly duplicates, such as google japan, google india, etc.) i think notable interest is that twitter stands out, with Scala and Ruby. Those with perl are probably going back to the first dot com era (aka Web 1.0, ~1995 to ~2002). At that time, perl was basically the only game in town (secondarily: Java). (i don't recall what amazon and ebay were in... was it perl or php? how about imdb.com?) most php follows starting in early 2000s, that's when PHP quietly surpassed perl in all battle fronts. it'd be interesting to know what some of the chinese sites uses, and porn sites (e.g. livejasmin, xvideos, youporn) as for Microsoft sites... are they in C/C++ and or dotnet?
