Well, as stated before, it is an extra profession. So it's in your best interest to level it as fast as you can. It will surely generate some money as do the other professions.
Remember, when cataclysm comes out everybody starts with 0 points in archaelogy, so if you're quick you might be able to generate a lot of cash (depending of the value of the rewards and the number of archaelogists).
It will definitely be interesting, I remember switching to inscription when LK came out, immediately wanting to switch back... The new profession's market always gets flooded and it just doesn't make economic sense. The only boom is within the first week. As you can see I'm all about profit in WOW.... It will be interesting and I'll have an alt pick it up, it's too costly to switch my main's profession.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
