Seeking expert medical advice? The Internet seems to invite us to dispense altogether with consulting a doctor in person. When I Googled "expert advice" and medicine, I got 1,650,000 hits. "Expert advice" and "psychology" garnered 950,000. (Your results may differ.) Sites such as Kasamba (www.kasamba.com) and AllExperts (http://allexperts.com) offer expert counsel on just about any subject.
