There's a lot of people writing stuff about Google+. (see here for example).
Now and again though you come across a blogger who's doing more than just regurgitating the latest update from Google, or writing yet another article like "7 Reasons to Plus".
+Jonathan Schofield (Circle him) has been writing great Google+ articles on his blog urlyman.blogspot.com that range from in-depth discussions of Blogger and Reader integration with Google+ to great ideas on how to improve the look of URLs in Plus.
Definitely a blog to follow and someone new to circle on Google+.
