Where do people go for revews / opinions on lenses?

I've been a Canon user so the lenses are pretty familiar to me, but don't know much about the other brands.

There are countless sites that do camera reviews, but lens sites are few and far between (IMHO)

kenrockwell.com for informed opinions on Nikon lenses.

I go to that guy on my msn list
And also check out what people say online,
but, usually, if i really really really really want it, reading a bad review won't stop me from getting it

First stop for me (though there is often a delay before they have the latest lenses):

DPReview mostly, the forums there... and more lately, the people in my Camera Club.
