Reply to this post, and I will tell you my favorite icon of yours. Then post this to your own journal using your own favorite icon.
I really can't pick a favorite; I like having lots of icons for different moods, different kinds of posts and comments, fandom versus not fandom, etc. So I chose this one because I think it's pretty -- I like the colors and the crop -- and because I don't use it very often.
I find memes like this interesting. It makes me think about how we present ourselves online, and about how other people see us.
