Actually, I do really like LISP a lot - I studied all of Steele's book and read a lot of the Reference Manual (hundreds of pages available online). But with Perl it is so easy to do fairly complex things (using available modules.) E.g., I wrote my own webmail and web news reader programs in about a day. Also, Perl has to be the ultimate in text searching and manipulation; in some sense that seems like one of the most important things that one can do - after all, most information that humans are concerned with can be expressed as text, and if one can deal with and manipulate that, what else is necessary?
Of course, all programming languages ultimately do the same things; only the style (and built-ins) differ.
