From the detailed graph it's shooting up like a rocket. 1% in the last 1
month? LOL. The search counts must have been riding on the coattails of
Angry Birds. (Rather, the coattails of iOS and Android mindshare.)
More likely that's Corona SDK, not Angry Birds.
Would be interesting to see when the percentage will dive right down
again. If you look at the graph for Go, it had a big hump at the
beginning of the graph, then tapers off a lot.
Hard to quantify anything, since it is not a measurement of quantity --
it is a fractional value of a collection of languages. By their measure,
even Ruby is steadily sliding downwards... or is it just due to a bigger
total of hits? Still, TIOBE is a convenient gimmick for bamboozling the
management to support your favourite language...
