This is going to go right over some people's heads, and make other people's eyes roll.
When I modify any kind of computer code that I don't write from scratch, I try lots of different alterations until I get the result I'd like. Although I'm pretty good about going back to delete changes that didn't work or did nothing at all, I still tend to end up with a few lines of code that aren't serving any purpose (either because I forgot to undo those changes, or because I later found a better way to achieve the same effect.)
Knowing I have stray lines of code in a program bugs me!
So I spent two days going through my template line by line, with a brand new fresh "Awesome Ink" Blogger template (which is the base for my current template), re did the hacks from scratch, and tested each remaining line of altered code to see if it was doing something useful or not. If not, it didn't make it into my final copy.
The result is a "cleaner" blog template - At least on the code side. The final product (the blog) looks exactly the same. There's no difference in it visually. But I know the code has been cleaned, and for some odd reason, that makes my brain happy.
