Thanks for all the info, interesting stuff. I haven't seriously considered it, but from what I hear it sounds like something I would like. I have no real plans of leaving my current job - they pay me well, gave me tons of great training, sent me to London for a few months, and just treat me very well overall - but it is not the job I pictured myself doing, nor do I have a passion for it. But it's my first job, so its all about gaining experience for now.
Maybe in the future I will do a bit more research into becoming a TA.
