First App/Script. Any sort of advice would be greatly appreciated

Alright, I've cleaned up my first ruby endeavor. I've added methods,
have tried to keep it DRY. I have also simplified a lot of complexities,
mainly of course, by the methods.
I'd be really grateful if you guys had a look at it, and could advise me
mistakes/what to improve upon/better ways to code some function/etc.

Here it is: https://github.com/Vshan/listy-fly/blob/master/listy.rb
and the repository: https://github.com/Vshan/listy-fly if anyone's
interested.

Thanks a lot, I'd be really grateful for any sort of help.
