I'm surprised that Scheme is not mentioned. If you consider it to be just a dialect of Lisp then Lisp+Scheme is probably as popular as some of the languages listed as succeeding for popularity. By my count, the combined Lisp+Scheme language has a 1.42% rating on TIOBE, which makes it more popular than Ada, ActionScript, C*, Lua, R, and others. Also, most of the favorable statements about embedding Lua or Tcl apply to Scheme, which continues to get embedded in plenty of important things.

I guess I just don't get the methodology behind the popularity list.

Also, my bet is that Lisp/Scheme would have been even more popular if there had just been one implementation as opposed to a confusing constellation of standards and different implementations. The language is easy to implement so the implementor:user ratio is too damn high.

Agreed, if you're going to list Basic and Pascal because they are easy to implement, then Scheme seems like a no-brainer for inclusion. It probably is the most common language for Baby's First Interpreter.
