While I agree, what's maybe more interesting is that a community of Java users would "do it all over again". Could be blub programmers not being able to see up the chain, could be normal human comfort tendencies, but it could also be "legit".
Agreed. There are lots of these language surveys. You can find aggregates through http://langpop.com/
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.
I strongly suspect that other sites, like Hacker News for example, would generate different results with a different leading language.
