As I understand it, this is just a ranking of popular search terms. In other words, there are now sufficient people searching on "Visual Foxpro" to make it appear on a list of most searched TERMS. TIOBE doesn't really legitimize Visual Foxpro all that much merely by saying that more people are curious, nor does a lower ranking lower it's standing in my eyes.

What it doesn't say is how many new applications are being built with Visual Foxpro.

However, I *am* continually surprised at how many places I find the Fox!
