Rood..
There are now roads connecting everyone's houses, courtesy of the L-Rock Public Works Division.. including signposts with names / arrows!
I forget where everything is in relation to spawn, but I think Eric's place is closest (the beach house). North of him is the Burning Man monument. Hang a right after that to go to Jon's place, or go straight ahead to Pump Palace. From there, you can head off to the left (west) to Aaron's Imporium of AAAAAAAAAAARON or you can head out farther Northwest to my place (ShopVac).
There's also roads to two of the NPC Villages (one north, one south). Other than that, it's a big wide open world.
