YouTube has a normalized weight of only 5.73%. > Also I noticed: "The first 100 pages per search engine are checked for > possible false positives and this is used to define the confidence factor" > - the confidence factor for Ada is not publicised. That could be the explanation... Anyway, the idea of a "transparent" index, with the same rules, but with publication of all figures, could be a nice project. Of course automatized... How complicated would it be to parse the HTML page returned by search engines ? For instance, the Google request gives somewhere in the HTML code: *<p id=resultStats>* Results <b>1</b> - <b>10</b> of about <b>1,440,000</b> for <b>ada programming</b> Matching the above tag, the result is at reach of the hand. Maybe some HTTP request to do with AWS ? Any hint is welcome, I'm doing the rest of the code :-) Gautier

There is also http://langpop.com/ which I find slightly more realistic based on my own experiences, although that doesn't show Ada in very popular light either. -- Tero Koskinen - http://iki.fi/tero.koskinen/

That would not be a big issue for me - provided the conclusions can be reproduced. I only have something against dubious statistics... G.

I hadn't realized how silly the TIOBE index is until you explained how it works. Another data point: http://www.blackducksoftware.com/oss/projects#languageos Still can't draw any real conclusions about the software industry from this data point, but it least it is not meaningless.
