The new favicon doesn't really stand out well - it blends into the background of my tabs. Obviously this isn't a universal issue, but I'm just using standard themes. A white (or other color) background might fix this without sacrificing design.
It should be simpler, letters can be bolder, and there is no point trying to fit the word "wiki" in a favicon, a bar on the same place would serve the same role, but easier to distinguish.
