most people change their avatars after a point
this is the first time i've had a pony avatar for more than a few hours since ever (saw it, thought it would work, it did)
it depends on what they want, i suppose. i don't actually know what motivates people to have and change avatars
several who have had pony avatars have changed to other subjects and have eventually came back to a pony avatar, and then to a new subject, and so on. just preference or what they want to have in that little box i guess
