If you're shooting in good lighting conditions and are just turning around and posting them on a website hoping people will buy them -- then jpgs are more than enough. RAW is really good for tinkering with when lighting isn't optimal and you need the shots. RAW gives you the ability to adjust a bunch and save some images that might have been taken in marginal light.

If I'm shooting a race event that I'll sell images to a magazine -- I'll shoot raw so I can rescue missed exposures.

If I'm shooting around the house -- I'll still shoot RAW because I'm too lazy to change to jpg.

If I'm shooting a model -- I'll shoot raw so I can play with the images in Photoshop later. I guess all those years in graphics has taught me not to leave well-enough alone.

RAW gives you more data to adjust. I use Lightroom and Photoshop CS3 to edit and play with my images. Lightroom is great for a quick sorting and adjustments and Photoshop is great for finishing and monkeying with the images. Every now and them I use Corel Photopaint (like Photoshop) to play with the images -- it has different filters and effects.
