I came upon f/1.0 but couldn't tell you how I got there if you offered me a fistful of money.
Ed Zawadzki has a very nice blog, with a bunch of instructional and educational posts.
What first brought me there was a 4 part series he is doing called "The Nuts & Bolts of Off camera Flash", you will find part 1 here, and part 2 here.
After reading these (well written) posts I started snooping around his blog and found other good things, like:
Shoot Fireworks Like a Pro
The 15 Second DIY Adjustable Snoot
Quick & Dirty Seamless Backdrop For Small objects
So take some time and go visit Ed at f/1.0 and do some snooping of your own, you'll find some really good stuff.
