I feel st00pid now. That would actually make my home a bit easier to see from a distance, too, on long journeys.
Aww, don't worry about it. We're all in this together. The torches also attract animals at night, so you'll always have a ready supply of pork, leather, and wool.
When I go exploring I usually leave a trail of torches and cobblestone behind me to mark my path. Then later when I get to the Nether I make nice big flaming beacons on pillars to mark my house.
Oh, and since I just posted shots of my house over on the Minecraft forum, might as well put them in here too.
Heres my current treehouse. Gotta love the view.
It'll look a lot nicer once I finish the big freakin' airship on the right.
