The Saturated Digital Image

As a professional photographer who’s making the switch from film to digital, I wonder how other pros are dealing with color saturation. On many photographers’ websites, the photos and portfolios look to me to be oversaturated, which makes me wonder about claims that Velvia is unrealistic because it’s so saturated. What’s a "fair" level of saturation in the digital world, and is there any standard in the publishing industry?
