TPCI - TIOBE Programming Community Index

The February Tiobe Programming Community index is out. Last month's showed ColdFusion at 16 and this month it is at 18. This does NOT appear to be because CF's popularity is dropping (last Feb CF was at #30), but rather there are a couple other languages that are a bit more popular right now. What I don't get is Visual FoxPro. It is #16 for Feb...are there really that many people out there using it? If so, why? It's also interesting to note that C, PHP, Perl, and Python are all decreasing. Java is still #1, while VB and C# show continued growth.
