It can also be a great place to get comfortable dealing with high level business people, Fortune 100 executives, etc... You have to be able to (or learn to) communicate clearly to the super technical folks they bring, and to the CEO who can barely use his e-mail. You get very comfortable speaking in front of a large group, and you learn to think on your feet.

I did it for a few years, before the travel burned me out, and I feel I learned an amazingly amount of useful skills from it. Stuff they can't effectively teach in school and that you can't learn coding in your living room.
