Pascal (35708)<p>I took the list of programming languages from http://en.wikipedia.org/wiki/List_of_programming_languages and downloaded page view stats from http://stats.grok.se/.<p>The following entries were removed from the top list:<p>- XML, HTML, LaTeX, PostScript, Batch (Windows/Dos): I wouldn't classify these as programming languages.<p>- MUMPS, COMPASS, ChucK, MATLAB, KRYPTON, Inform, Arduino, Oracle, R: I assume people were actually searching for something different.<p>If you are interested, you can find the full list (including page count data for the last 24 months) on Google Docs: https://spreadsheets.google.com/ccc?key=0AvObTduyoRZ-dHVzbzgxeC1ZZnE4ZXJDN0FyUTZCNmc&hl=en&authkey=CKLB1ccE
Why wouldn't you classify PostScript as a programming language?<p>From its page on Wikipedia:<p>"PostScript (PS) is a dynamically typed concatenative programming language"<p>Just because it's mainly been used as a page description language for printers doesn't mean that people haven't written applications in it - Arthur van Hoff even wrote a C to PostScript compiler in PostScript (pdb - allegedly standing for "Pure Dead Brilliant" - it was written in Glasgow).
Interesting -- I am much more likely to read the Wikipedia page for a language I don't know than one I do. Not sure how to interpret the stats in that case.
