Twitter has just unveiled its simplified logo: a plain, iconic blue bird. The company says that "from now on, this bird will be the universally recognizable symbol of Twitter," and that "there's no longer a need for text, bubbled typefaces, or a lowercase 't' to represent Twitter." While the logo shift is a refinement rather than radical shift, the move further simplifies a brand that's already well along in its march towards ubiquity. Twitter says that "our new bird grows out of love for ornithology, design within creative constraints, and simple geometry," and that "a bird in flight is the ultimate representation of freedom, hope, and limitless possibility" — a lofty ideal to be sure, but some birds may end up flying higher than others.
