The old one consisted of the characters "Lw", the abbreviation for the site name, with colors resembling the site's color scheme. These are all straightforward indicators. While I understand the intention of the new icon, it is not nearly as straightforward.
LW appears to have acquired a new favicon, "<X" in place of the prior "Lw". This change wasn't announced and I don't know what the new icon means. Can someone explain it to me?
