But beware lag time.

That is: Some languages aren't suitable for general use. Some aren't... and then they are. But popularity probably correlates with how suitable the language was at least two years ago, and maybe more like 10. (Call it 5 as a compromise.)

So popularity doesn't tell you that the language is unsuitable now. But I agree, there is a correlation. Programmers for the most part aren't stupid sheep, afraid to use something new.
