TIOBE index

[1] TIOBE stands for The Importance of Being Earnest, the title of an 1895 comedy play by Oscar Wilde, to emphasize the organization's "sincere and professional attitude towards customers, suppliers and colleagues".

[2] The index is calculated from the number of search engine results for queries containing the name of the language.

For instance, in April 2004 Google performed a cleanup action to get rid of unfair attempts to promote the search rank.

Maintainers specify that the TIOBE index is "not about the best programming language or the language in which most lines of code have been written",[10] but do claim that the number of web pages may reflect the number of skilled engineers, courses and jobs worldwide.

Tim Bunce, author of the Perl DBI, has been critical of the index and its methods of ranking.
