The top 10 programming languages?

eWeek has listed the "top 10" of programming languages one should learn based on their popularity in companies seeking programmers. Of course, everybody has their opinion when it comes to what everybody should do or learn, but it is interesting to see AJAX listed as a programming language. Huh? Other than that, the usual ones like C, C# and Java are listed. Why list so many scripting languages on the top 10? That escapes me as well.
