If I'm enthusiastic about photography as a hobby, am I deemed an "enthusiast" or a "hobbyiest"? How do manufacturers design, market or otherwise aim equipment towards one group or the other? Are there really two groups?

How you refer to yourself is up to you.
The only defined distinction is between a professional and a non-professional (whether you earn a living or get paid for photography).
References to "prosumer", "advanced user", "enthusiast" etc. are ambigious at best. It's your call.
You can be what you want to be (without joining the army either).
