C Programming Language Back At Number 1
derrida writes "After more than 4 years C is back at position number 1 in the TIOBE index. The scores for C have been pretty constant through the years, varying between the 15% and 20% market share for almost 10 years. So the main reason for C's number 1 position is not C's uprise, but the decline of its competitor Java. Java has a long-term downward trend. It is losing ground to other languages running on the JVM. An example of such a language is JavaFX, which is now approaching the top 20."
but shouldn't it really be at number 0?

Go ahead, read it for yourself, and tell me how this is supposed to give any meaningful results. They aggregate together things of all kind, to the point where an aggregate doesn't make any sense at all (I mean, hits such as "programming in PHP sucks" or "you must be an idiot to write production code in VB" would count as +1 for PHP and VB, correspondingly!). You can have one language having many job postings, another having many books, and yet another having many basic "how to?" questions and dumbed-down tutorials, and they'd all get the same rating.
In any case, most certainly, at these numbers (Java 18.051%, C 18.058%), speaking of one overtaking another is completely pointless, given the margin of error.
Anyway, if you want to know how popular a particular language/technology is, the simplest - and much more accurate! - way of doing so is to check any popular job search web site. Just keep in mind that preferences vary in different regions, so if you are making career choices, stick to local/national postings, and if you want to see an overall worldwide trend, you have to aggregate data from enough sources.
The index is updated once a month. The ratings are based on the number of skilled engineers world-wide, courses and third party vendors. The popular search engines Google, MSN, Yahoo!, Wikipedia and YouTube are used to calculate the ratings
I feel so much confidence in these numbers.
