Grinder isn't on many of the lists of Web testing tools I've seen, but it seems to be quite mature & gets some good press. Let me know if you try it and like it.
Charlie Stross & Perl
One of my favorite new sci-fi authors is a guy named Charles Stross. He rivals Iain Banks for plots that are turned 2 degrees to normality, and is a hacker/sysadmin by trade. It was therefore distressing to read his take on Perl:
"""
... then along comes Randal or Tom or one of the other Perl Gods, and they deliver a half-line-long command that resembles line noise, is three times as efficient as the other solutions, and leaves you scratching your head.
"""
Apparently this is a desirable feature of the language!?
Anyway, I have to admit he wrote the best description of Zope I've ever seen...

p.s. The Atrocity Archives is an amusing blend of a Cthulhu-like mythos and UNIX sysadminning. Let's just say that LARTing takes on a whole new meaning...
