Here's a cool use of publishing-on-demand technology: Cameron Kelly proposed to his girlfriend Angie Kreimer via a 113-page self-published book he created at Lulu.com -- 50 Reasons Why You Should Marry Me and 51 Reasons Why I Should Marry You. The book includes 101 pages of text and 44 color photographs. "It's a sort of prose-poem, with pictures," Kelly said. According to a Lulu.com press release, some of the reasons he claimed he was marriage-worthy included:

- I clean the bathroom every week.
- I'm going to look like Sean Connery when I'm 65.
- You don't even have to change your initials!

Apparently the book was met with a one-word reply -- "yes".

I kind of love this idea. It takes the genius of publish-on-demand technology and pushes it to its logical extreme: A book published for a niche market of precisely one person. That's pretty far down the Long Tail! Though who knows? Maybe other people will buy it and read it. It reminds me of teenagers using PowerPoint to craft corporate presentations arguing why their allowance should be increased.
