In my case more reasons for than not.
Gives me something tangible and universally recognizable, applicable to my current field, and opens the door for a lot more than what an arts degree will. I've been working with consumer level finance, sales training, including developing an entire finance sales web platform. Not just from a conceptual standpoint, but technical. Just some basic front-end development. I'm no a professional, but I can get pretty crafty with them internets.
Not exactly the track a philos major follows though.
My experience says I can be capable of things that my degree says I'm not. Usually it just gets a chuckle! So I'd like some more formal training.
