You may have noticed ... okay, you probably didn't, so I'll point it out right now. Depending on which browser you are using, and whether you use multiple tabs, you may be pretty used to the little white "B" with the orange background. It's the little default icon for a blogspot blog.
Anyway, you probably haven't noticed, but I've recently customized mine. You might not be able to tell but that's a tiny Yoda up there, which is the same, albeit smaller, icon used for my comment avatar.
If you're interested in changing your own favicon, you can feel free to email me for assistance, but first read this tutorial, it's the one I used and it's pretty easy to follow.
Having a custom favicon is really a pretty trivial thing. It's not going to bring more traffic to your blog, it's not going to make an agent sign you, but it is fun, and it only takes a couple minutes to play with.
Anyway, I'm off to bang out another chapter in my re-write. Have a wonderful Friday, readers!
