Well, after saying over and over to anyone that would listen that I wanted the 3-column format in Blogger, I finally went ahead and did it! There are still some things that I would like to tweak, but overall, I'm very happy with the new look. All links should be on the right-hand side, and all other information should be on the left. Hopefully that helps all of you in your browsing :-)
I used The Blogger Guide to switch up my template and had no issues with it at all. The tutorial works like a charm- so if you're considering a switch, I'd highly recommend that website.
I also tweaked my Labels section slightly, though I doubt anyone else will notice. I want to get rid of as many labels that are associated with just one entry as possible. That may take a while... but I hope to be a more careful labeler going forward.
