Pwinget, I think the beardeds get the most attention for the reason Bonnie stated--many of the folks who contribute to the Iris Forum live in areas where only the beardeds are successful. We tend to talk about what we know.
Our moderator, PollyK, is a devotee of Siberians and has some lovely photographs she has contributed. I have some Spurias I just put in and am eager to see what they do next Spring.
