Visual FoxPro is a Rising Star

A report from TIOBE Programming Community indicates that Visual FoxPro has raised its position from 51 to 20.

Rising star this month is Visual FoxPro. It jumped in one year time from position 51 to 20! It is interesting to see that there is a whole bunch of "new" programming languages (such as Visual FoxPro, ColdFusion, Ruby, D, and ActionScript) trying to get in the major league, but none of them is capable of holding a top 20 position for more than a couple of months.

Huh? Is it a predication or what? Why can't VFP stay for more than couple of months?
