Elizabeth Foss shared this blog post talking about the newest Google Reader gadget. It is great! You add the "Next" button to your bookmarks bar and it takes you to the blog post that is next in your Google Reader line up. So now, I don't have to create tabs of all those posts that I want to go leave a comment on, I am already there!
The first time I tried it, I only had 3 new items. When I clicked on the last one, I wondered what would happen if I clicked "next" again. See for yourself! Gotta love computer nerds!
