Usability 
Techdirt is Mike Masnick's blog covering technology and media. Mike's a very good tech business analyst, particularly in the areas of privacy and intellectual property and he's made Techdirt a hot property. It's on CNET's Blog 100 list, the Technorati 100 and lots of other "best of tech blogs" type lists. There's a "Lite" version (techdirt.com/inOriginally the front page contained the full text of the 20 latest articles - about 60 KB's worth. which meant that it was too big to load on many mobiles. But after I blogged about my concerns, Techdirt made some adjustments cutting the number of posts per page to 3 which reduced page size to only 10KB. The format of Techdirt Lite is rather cool, it's the simplest possible UI, just open the site, start reading and read until you've had enough. I don't think pagination hurts the reading experience, having to click on Next every 9000 characters or so is no great hardship considering it would makes the site usable on all mobile browsers instead of the 30/40% that could handle the 60KB version. A side benefit is much faster page loads, a real issue on slow networks.
