That list is ridiculous...Lisa, Heather, Meghan, Alana, and Irina are FAR more successful than Julia Dunstall.
Personally I'd arrange that top 10 like this:
1. Stam (because she is successful as a model, AND she has sort of a "celebrity" like status now, and a lot of people recognize her)
2. Daria
3. Coco
4. Alana
5. Meghan
6. Heather
7. Irina
8. Lisa
9. Julia
10. Johanna Stickland (doesn't work much anymore but she's still more successful than MArla Boehr)
