I changed the sidebar of the Exploration blog. Instead of using the link list function, I created a Blog Roll (Blogger's code for an RSS reader) of all the explorers' blogs. The only problem is that the order will change based on who updated the most recently. Which means each time I do this, my blog will go to the top...so much for lurking!
Anyhoo, if any of you want to use the sidebar as your RSS reader for Exploration #4, it totally counts and is much more convenient than having yet another site to go to (though your blog could get a bit messy if you add to many...up to you).
