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/.
The following entries were removed from the top list:
- XML, HTML, LaTeX, PostScript, Batch (Windows/Dos): I wouldn't classify these as programming languages.
- MUMPS, COMPASS, ChucK, MATLAB, KRYPTON, Inform, Arduino, Oracle, R: I assume people were actually searching for something different.
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
