I've got a friend who uses a screenreader, too, so being able to see the icon description is good.

The comments bit, though... nice idea, but where it's used to credit the maker of an icon, I think it'd look better if it came up as username or username rather than showing the HTML code - it'd be neater and tidier, because we don't see the HTML code in use, only what it does. I doubt that even a screenreader tells the user the HTML code string rather than the emphasis (if it even does emphasise whatever in the first place). That's if you end up deciding to keep the comment bit showing of course - if you decide to take that bit off, this becomes a moot point! :D

But I love the new option to show my icons in keyword order - after all, that's the order we see them in when picking an icon to add to a comment or post.
