I'm icon shopping right now! I've left a bunch of slots open in my user pics, and I'm going to be filling most of them in over the next few days. 

I'm kind of picky about icons. I don't usually like the ones with text; I'm by nature highly textual, so words on top of my pictures distracts me and makes the icon less about image (which I think it should be) and more about word, and overall I feel the impact/message has been lessened or even lost. I also prefer icons with colour. Most of my icons are fandom-based, but my default one was chosen for personal reasons. I tend to like icons that convey a very specific tone; I have an icon I use pretty much exclusively for things that are depressing, from world news to angsty fic posts. I have a stalker icon for when I want to comment on someone's post and let them know I like them/their writing possibly too much to be healthy. 

What (if any) icon preferences do you have?
