By recently looking at the TIOBE Programming Community Index (Sep 2012) I noticed the following order:CJavaObjective-CC++C#PHPWhen looking at the tag frequencies of stackoverflow however, the situation is as follows:C#JavaPHPJSAndroidjquery (JS)iphone (Objective-C)C++(Java takes the lead when accounting for Android tagged posts w/o a Java tag). JavaScript also likely has surpassed PHP in total numbers of programmers?I realize the tag-frequencies may not be the best indicator, but it is likely a sufficient  measure nonetheless.What am I missing that explains this discrepancy, especially for ANSI C and JavaScript ( #11 in the TIOBE index)?Links:Wikipedia TIOBE indexThe Transparent Language Popularity IndexJobs Tractor language trendsGithub top languagesLangpop
Why is there a large discrepancy between the stackoverflow tag frequency and the TIOBE Index?
