I came across this site that tracks and ranks the use and popularity of all the world's programming languages. This site is called "The TIOBE Programming Community index". Anyway, what really astounded me was the sheer number of so many different programming languages around. Hell, about 75% of them I have never heard of! For an example, these are some actual names of apparently legit programming languages out there in use:
"Awk"
"Groovy"
"MOO"
"SuperCollider"
.....and the list goes on! There's even one called "Boo"!
They also have a top 100 list of the most popular programming languages in use today, and to tell you the truth, I was a bit surprised at who's #1! I for one, thought it would be C++ or C#, but no! But hey, at least good' old C came in at a very close #2 in the list.
By all means, see for your selves: http://www.tiobe.com/index.php/content/paperinfo/tpci/index.html
