Not sure if you're aware there is a new version of Blogger out! Nothing changes for the readers. The URL etc. stay the same, but there are some nice additional functionalities such as post labels. I have an index page, but haven't really kept it up to date.
I do have to upgrade the template in order to use the new functionalities. I'll do my best to make the transition as seamless as possible, but if glitches occur I apologize in advance.
