Yeah, pretty much what @
retep998 said. Servers nowadays are so short-lived and there are a ton of them. Literally, tons. Servers like ExtaliaMS have remained open because they started a long time ago, have received huge donations, and now have the money to keep 1500+ players online at once. Other popular servers, have 200-500 players on at once. For your server to be noticed and played, especially when the populated servers already exist, you would need something very special.
Good luck if you try it though! We're not trying to be discouraging, just honest.
