Blogger did a great job with removing that horrid ad banner and replacing it with a fun, functional, and sleek toolbar. The search feature for searching a single blog is a fantastic addition (albeit Soople has reminded us of Google's shortcut for this for some time). The best thing is obvious the "next blog" random blog hit. I've looked at my stats and some others and for the past two days they have been filled with "wierdness" as referrers have inexplicably come from completely unrelated blogs. Everyone's hits are up! Of course, our metrics for judging how we are promoting our sites are completely thrown off now!
Obviously the blogsphere is enjoying this feature quite a bit! Thanks Blogger.
