I've been reading Strobist for a few months now, and while I haven't gotten the equipment to do the shooting I want to do, I've found the site very informative.
I'm a "lighting guy" at heart. I love what light can do to create mood, change shape, or generally change how an item or scene appears. However the lighting I'm used to working with is high-wattage, high-temperature, and high-cost. Strobist shows a lot of ways to achieve some very cool effects on a (relatively) low budget. The Lighting 101 section is a great introduction to setup and equipment on a budget. If you want to kill some time, and see the effects that lighting can have, look through the Strobist Favorites on Flickr as well.
