When I first started out at RS a year ago, I wanted an avatar that at least stood out a little bit more than the rest, since it was such a huge crowd over there ("only" 2,874 at the time), so I went with their avatar of the Imperial Royal Guard figure, which was a nice bright and noticeable red color.
Well, when I migrated over here several months back, I wanted to stick with the same character since that's what I was known for, and Chris had a WAY cooler looking Imperial Royal Guard here at JD, so I went with this one instead. Looks kinda menacing, I think...
Mike, where'd your customary Biker Scout zipping through the trees go? Get tired of that one?
As for the other collecting sites out there, well, I think that every site has it's pros and cons, as do we, but I definitely have no ill will towards any of them at all. Though I'll still pop into a couple of the others from time to time, I prefer to hang my hat here as well since it feels the most personal, and I really feel like I'm building friendships here, beyond just talking Star Wars, and that's important to me. I also really like that we've got some of the most knowlegeable and insightful collectors out there, who really like to "talk shop" about our favorite hobby...
