In all the hoopla over the redesign of Twitter.com, a key development seems to have been overlooked: Twitter has a new logo. In a shift in aesthetics seeming to mirror the fact that everyone’s favorite little micro-blogging site is growing up, gone are the elementary-school unicorn-and-rainbow-style bubble letters. Taking their place are silhouettes sleek enough to adorn a pre-teen’s first skateboard. We are so proud.
