Please note that this survey has been done by a Java community website.
I strongly suspect that other sites, like Hacker News for example, would generate different results with a different leading language.

For example, PHP is highest on Craigslist's job ads. Javascript wins on Delicious's bookmarks. As someone mentions in another comment here, Ruby takes the top spot on GitHub.
These language surveys indicate more about the community a particular site has than anything else.
p.s. The TIOBE index is another aggregation: http://www.tiobe.com/index.php/content/paperinfo/tpci/index....
Although I think the choices are exclusive (no "choose three"). Also, I believe you need a minimum karma.
