This may have already been posted, but I found this article and thought it was interesting:
http://www.andaman.org/BOOK/reprints/weber/rep-weber.htm
The author uses six criteria (number of primary speakers of the language, number of secondary speakers of the language, number and population of countries using the language, number of major fields using the language internationally, economic military and financial power of countries using the language, and int'l socio-literary prestige of the language) and finds the 10 most influential languages to be:
01. English
02. French
03. Spanish
04. Russian
05. Arabic
06. Chinese
07. German
08. Japanese
09. Brazilian Portuguese
10. Hindi/Urdu
The article was printed in the mid-90s, and certainly a lot has changed since then, but what do ya'll think?
