Here's a tip for anyone looking for their avatar: Look in places similar to your avatar's color. Notice how blue avatars are all in one place, yellow avatars are all in one place, and black avatars are all in one place, whereas rainbow or highly multicolored avatars are absolutely random in position.
I used this strategy to find Rotondo, Bones4, Skip, Bester Bageler, Furling, and Redconer.
