link rel=twitter - A proposal for mobile browser makers
It is generally easier to share what you’re reading on a mobile device than desktops. Mobile browsers allow you to email, share on Twitter and, with the latest Chrome and iOS 6, share on Facebook.
One advantage of Twitter’s sharing widget aka Tweet button is the via field. Mobile websites cannot afford to add bulk by loading the Twitter widget. So perhaps mobile browser vendors should start supporting a way to add the via hint. It would work like this (without the mangled smart quotes that Tumblr introduced below):
<link rel=”twitter” href=”https://twitter.com/Diffen”>
With that in your <head> the browser now knows the publisher’s Twitter handle and will automatically append (via @Diffen) to the tweet text.
