Technorati been in the go for some pretty bad publicity in the past few months or so, although it's been getting much much better lately (mainly from its recent funding series'). Today marks their third anniversary and rightly so, they've relaunched with a new upgraded design and minor features and changes. I didn't think their old design was bad at all, although this is much better.
In the new interface you will notice much cleaner and (in my opinion) ergonomic placing of things. Amongst many other new things, there is a Discovery section (which is essentially 'browse by category'), a meme-style Top Blog Posts, and Featured Bloggers. They've also changed the style of the Technorati Top 100 with new categories and sections.
I'm very pleased with this change and certainly shows that after all they've taken almost ever since they launched, Technorati is finally going in the right direction. Next step in my opinion would be to make it more accessible to the mainstream and broaden their focus, although that might still take some time to acheive.
