fn main() at the top or bottom?

Hello! I'm pretty new to rust, I've been reading / lurking for a bit, getting the feel for the language before diving in. Just wrote my first simple http GET request and I'm liking it.

Since rust can have the main() function either at the top or bottom, does anyone has any real strong opinions on this or function order in general? I'm used to just putting my main entry at the bottom because of tradition, but I've worked on some javascript files where folks like to keep their main function at the top vs python having the main at the bottom.
