I've been bored with the look of my blog for some time, now. When Blogger brought out the beta version - with Google - of their new software, I bit. It's pretty painless, but those of us who'd modified the standard template have to plan on recreating them. Still, it's not that tough.
I was able to put back in the Memorial to the 9/11 victims. To me, that was VERY important.
I dedcided to lose the Tags feature - I just didn't find it that useful.
