I've been a bit annoyed with the fact that Blogger doesn't support inline comments. I ran across this great site, Blogger Buster, that has all kinds of tips for using Blogger.
First I tried the hack for adding a favicon. Which you should see now on my blog.
I've also enabled inline comments using this tip from Bloger Buster.
I've added inline comments using this on both Hacker Class and Saigon Files. Being a bit anal, I took the original template code and checked it into my SVN repository before making the changes. It also makes it simple to see the differences in the code. It's not a lot, as you can see in the diff above.
So give it a go, try commenting on my blog and see how it works.
