I'm a bit of a burnt out travel agent, having spent a good part of the last few years explaining to people why they should buy their tickets online and not with me.
However perhaps here there is a niche(!) for developing a site that could advise or direct a confused or novice traveler...
Like when you actually could save by using an agent,
How to sift through reviews when booking a vacation,
Why to choose a bed and breakfast over a hotel.
