Yep, an icon is something everyone can have an opinion about. I don't like the default one, not just because it looks awkward to me, but mainly because the colors are very invisible to me, and it's hard to find in the dock. For a while I used a replacement icon from the World of Aqua IV of the red robot from Ghost in the Shell, and I'm currently using the 'braces' icon.
I don't think I have to love an icon, but I should be able to find it quickly in the dock.
