In my opinion, the list does have some languages that never took of, but there are some that are significant
though may not have gotten real popular.
Certain languages have far reaching contribution even if they may not be the most popular language
or most popular currently. We are just beginning to appreciate Functional Programming. Soon when several
processors on a computer (and laptops) becomes a standard, ability to not just model, but implement concurrent
tasks effectively will become an important and pressing issue. We will soon be looking for languages (or at least
language constructs) that abstract it for us. I think it is an interesting time in the language space.
