When your crush adds you on Facebook, does that mean anything or not?

Okay so I have a little crush on this guy who I've only talked to yesterday at a party. It's funny cause we've been going to school together and we've seen each other around but I never got a chance to talk to him. Anyways the the day after we talk he adds me on Facebook. Now I know I should be taking this as any type of sign I'm just excited about it. Just wanting to know your opinion, does it mean anything or is it just normal.
