I certainly mean no disrespect to the author (since ingenuity driven by nothing other than curiosity should never be frowned upon), but the data seem suspect.<p>There are numerous small factors: anecdotally speaking I write code but don't use Twitter to discuss code (nor do any of my coworkers); I spend most of my day in Python and Java but if I were to Tweet it would likely be in anger about JavaScript or CSS or any of a host of other languages I must deal with that weren't included in the sample.<p>But more importantly, languages that enjoy vast market penetration are going to differ significantly in terms of public acclaim from those with small, dedicated, passionate user bases. And so for example it comes as absolutely no surprise to me that Haskell would rate higher than Visual Basic.
