>I am just curious as why people love lisp so much.

Lisp is addictive, like a hard drug.

Lisp is the original "programmable programming language".

Experienced programmers with no previous knowledge of Lisp should relish (or doubt in disbelief) at the features provided.

Lisp, at least Common Lisp (but other Lisp dialects as well) might claim to be the most powerful and versatile programming language (and environment) available.

CL can run pretty fast. At the same speed than Java on the oracle JVM, and if some tricks are applied it should match C and Fortran speed under certain conditions. CL code is extremely portable.

Lisp has been used for very high level tasks (AI, etc) and for low level tasks (operating systems for Lisp machines).
