What's the best way to learn LISP?
I have been programming in Python, PHP, Java and C for a couple or years now, and I just finished reading Hackers and Painters, so I would love to give LISP a try!
I understand its totally diferent from what i know and that it won't be easy. Also I think (please correct me if I'm wrong) there's way less community and development around LISP. So my question is: what's the best way to learn LISP?
I wouldn't mind buying books or investing some time. I just don't want it to be wasted.
The "final" idea would be to use LISP for web development, and I know that's not so common so... I know it's good to plan my learning before picking the first book or tutorial and spending lots of time on something that may not be the best way!
Thank you all for your answers!
edit: I read Practical Common Lisp and was: ... long, hard, interesting and definitely got me rolling in Lisp, after that i read the little schemer, and it was short, fun and very very good for my overall programming. So my recommendation would be to read first the little schemer, then (its a couple of hours and its worth it) if you decide lisp(or scheme or whatever dialect) is not what you where looking for, you will still have a very fun new way of thinking about recursion!

Try reading Practical Common Lisp, by Peter Seibel.
