The anecdotal feedback and data seems to suggest that Guest Bloggers Week was a success. Daily traffic went up by about 33% (of course that could be the Guest Bloggers themselves..coming back to see if people commented on their posts).
Side conversations/emails seem to suggest that other (non-commentating) readers enjoyed some fresh voices.
Much like immigration reform advocates, I am going to institute a "Guest Blogger Program."
I will invite 2-3 people per week to lend their opinions and ideas to the Blog.
We'll see how this social experiment works out.
