Usability 
Although it's been around since 2007, I just discovered the mobile edition of paidContent.org, a leading tech news site covering digital media including entertainment, publishing, advertising, marketing, and technology.
Founded in 2002, Paid content was acquired in 2008 by the UK's Guardian Media Group, publisher of The Observer and Guardian daily newspapers.
The mobile edition has a clean attractive design that echoes the style of paidContent's desktop site. it's a one size fits all design that looks and works well on Android and the iPhone but degrades nicely to be usable with the most basic of mobile browsers. There are few images, other than a logo, and no ads either. Page sizes are admirably small (the front page is only 15 KB). Most news items are short but there is no pagination of longer articles which can be as large as 56 KB. There's no image resizing either and images, while few, tend to be large
paidContent has three sister sites that use the same mobile template: m.paidcontent.co.uk and m.contentsutra.com which are the UK and Indian editions of paidContent.org and m.mocoNews.net which covers mobile media.
