Matt Brett just launched a new design. I really like the way comments are styled. The site has one of the best implementations of threaded replies that I have seen.
Subscribed to comments via email icon
Also, check out the icon next to user’s names denoting that they are subscribed to the post’s comments via email. A cool little detail that I haven’t ever thought of using with WordPress and the Subscribe to Comments plugin.
Overall a very nicely designed personal site!
