It's not that I don't or I won't, it's more like 'I haven't yet'. It'd be pretty pretentious of me to hope that other people will use my icons, and then for me to refuse to use others' icons myself. Just because I haven't yet, doesn't mean that I won't ever. Besides, I have used icons other than those I make before; I love using your Grinch icons at Christmastime. :)
