A good way to burn time for a while?

I'm at the point now, where all I really need to do is kill Titan HM for my relic. I'll probably get that done by tonight, being a tank. I'm not really ready to hop into BC yet, I wanna wait for some friends to catch up first.

Not being the type to whine about lack of endgame or lose interest, I'm wondering if there are some productive things to do outside of leveling another class to 50, and farming for more gear.

I want to say I'm interested in the crafting/gathering, but I'm just not sure yet. I'll inevitably give it a shot, but I don't want that to be my only reason to log on. Any suggestions as to things you've found to occupy your time would be appreciated.

Get all the minions, fight Behemoth and Odin, help your friend lvl up. Just off the top of my head.

Travel every zone with HUD turned off.. Game is a thousand more times beautiful then you first realize...

Get your relic and then stand around in Uldah all day! Naturally with attack stance on.
