We used to have the Gator Times (formerly known as Orange and Blue), but it went out of business. Either way, it was never close to being as popular as the alligator. It was only printed twice a week, and I couldn't stand reading the articles b/c of the mistakes.
Currently there is the Gator Standard, but it's sketchy to me. I don't know when it's printed, or even how to get it. If you happen to get one shoved in your face as you're walking to class... then you get one.
But to answer... the Alligator is very popular. You can find it everywhere on campus, and even some off-campus locations (i got it at a gas station once). Buses and classrooms are littered with copies....
It's just what you read when you don't want to listen to your professor.
