I would also have to agree with BigCeC43. I think that availability is one of the biggest things. Unfortunately, many people's (myself included) first/possibly only exposure to "pet" snakes is going to be through a petstore and what they have available, which if course would be your more commonly kept snakes. So, IMO, unless someone knows someone that is familiar with snakes of all different types, or has done alot of research on snakes and has some knowledge on them and the different types that thrive as pets and where to get them, then you get people that buy into what is common in the nearby petstores. Not that this is necessarily a bad thing, I love my snakes but it wasn't until I found this site that I was more aware of what people out there keep as pet snakes. And it wasn't until I came here that I even heard about some of the other snakes out there, like your Blue Beauties (I absolutely love yours BTW, might have to get a beauty for myself someday....)
