I love this but I would love it even more if it would support Wordpress. I migrated my old Livejournal (I know...) to Wordpress so it's like a record of my past ten years at this point. It'd be fantastic to have all of that as a physical item.
I was also thinking if you could integrate with Daily Mile (which I use) or services like that, that could be really interesting. I have some memorable bike rides in there.
