I don't think there's much of a gender bias involved. It is a bit difficult to tell with a web poll.
The last I heard, women were very slightly outpacing men when it comes to internet usage. That could sway the results, if only by a bit.
I suspect there are more male snake owners, but female snake owners are more social, and more likely to come to places like this to talk about it. That would be in keeping with general m/f trends.

Besides, guys already know everything, so they don't need to look up info. (runs to avoid thrown fruit)
