So, I'm a programmer so I know a few computer languages. Here's how I rank them, from most favorite to least favorite.

• Java - I just recently came to feel this way, and it's somewhat a reflection of the IDE I've been using, IntelliJ's IDEA. It's awesome. But meaningless for me to explain why. Anyway, I'm back on C++ and I miss it. Anyway, the great thing about Java is that it makes doing everything easy. Which, incidentally, is what makes IntelliJ good also - it makes everything easy. So instead of wasting your time figuring out obscure constructs or whatever, you can spend time writing meaningful code. It's amazing how easy and how fast it is getting something working in Java. Plus there's documentation galore online so you can always find what you need.

  The worst thing about it is that it's so darn slow. I wish Sun would be more amenable to seeing it a cross platform language instead of having these theoretical issues about the JVM. So that you could compile Java into native machine code. I dunno, I think that would make Java more attractive. Anyway, yeah, my favorite language.

• LiSP - I barely remember any LiSP now, but I'm one of the few people I think that have taken a dedicated LiSP programming class. It's absolutely unreadable, confusing and kind of limiting. But when you know how to use it, and for certain applications, it's awesome. Did you know emacs is written in LiSP? That's why your .emacs file has all the defun functions and parentheses all over the place. I dunno, it's interesting to me.
• C++ - The thing that makes C++ powerful is the same reason it sucks - you can do almost anything in C++. Like you can override the '+' operator for classes (I think). Stuff like that. So yeah, there's so much you can do in C++, and it's pretty awesome. It's just incredibly complex, and unlike Java, it's not easy to find what you need. Kernighan and Ritchie's C manual is both concise and complete. Very useful. Stroustrop's book is immense and confusing. His language is the same. But, it's still a lot more useful than C, if for the STL alone.
• C - There's a quote about C somewhere, "All the power of assembly with all the expressiveness of assembly." I dunno, in a lot of ways I still feel most comfortable with C, but in terms of usefulness, how quickly things can get implemented, it's probably at the bottom of the list. LiSP maybe is lower, but in certain domains it's a lot easier.
