This is the impression I get as well. VB.NET > JavaScript?
Here's what they say about their methodology:
> The TIOBE Programming Community index is an indicator of the popularity of programming languages. The index is updated once a month. The ratings are based on the number of skilled engineers world-wide, courses and third party vendors. Popular search engines such as Google, Bing, Yahoo!, Wikipedia, Amazon, YouTube and Baidu are used to calculate the ratings. It is important to note that the TIOBE index is not about the best programming language or the language in which most lines of code have been written.
And some of that "methodology" is seriously suspect.

Bing and Yahoo! are both front ends to the same search engine. Wikipedia, Amazon, and YouTube aren't general-purpose search engines at all, and it's unclear how accurate the results of a Baidu search would be for English-language search terms like "Javascript programming".
