My first attempt at something semi-dynamic is the location entry in the left column. I have another PHP page/script where I can submit my location and it writes it out as a file to be included here.
I also want to put a small calendar in the column for easy navigation from one day to another.
I have some ideas for creating traveller blogs. Now that they have an API for programmatically submitting blogs one can write a pre-processor. I've see many attempts at travel logs out on the web and there really isn't any consistency.
