Okay, so it's now been a little over 11 hours since I initiated the switch over to the new Blogger. Admittedly, I didn't think that it was going to be a couple minutes to transfer over my more than 2,000 posts, but never did I think that I was going to be out of commission for, well, 11 hours (and counting).
The changes aren't spectacular, but it's nice to see that the old template works fine. To implement some of the new features or to make them visible, you need to add some code, though.
