I know there's a name for those icons, but I don't remember it. However, I notice that the NWS is changing theirs for some reason. I notice that WU changed theirs when they remodeled the site.
I am attaching a picture of the old and new url icons for nws. The new icons are 10 and K and the old (darker blue) icons are C and N. Has anyone else noticed this? I could see the old icons better. The new ones look kind of florescent. I wonder why they have to change things that are ok to start with?
