I do. I love it. It helps me keep track of all your blogs without having to bookmark them or remember which ones I've checked when.
But one thing that it misses is the look of the blogs themselves. Last night I changed up our template. Call it a spring cleaning for the blog. If you're reading this in your Google Reader, you may want to pop on over to the actual blog.
And thanks, Google, for the new design templates. I had fun playing with them!
