I must say, the site looks more appropriately tuned on the mobile version. Not necessarily better, just a little less ill-fitting than on the desktop.
And if I had my way, I'd ditch the circle motif for avatar pictures. In fact, if they want their "buzz" to stick, a feature for customizable skins or themes (including color-scheme, font style and point size, avatar appearances) for your interface would be the "sets us apart" jewel among networks. Perhaps that's what they're eventually going to charge for. In the meantime, this place gets slightly uglier every time I tab back.
So, isn't that what early posts on a new site are about? Bitching about ultimately meaningless stuff it's not our place to voice ardent opinions upon?
