DisposableWebPage.com - Web Pages with Expiration Dates

The Disposable web page is here at last. Now the question is, what do you use such a thing for? Count downs, goal setting, ads, pranks, perhaps. The deadline's the limit, I suppose. Each page expires after 90 days (although you can set the kill switch to go off after a day or an hour). The site will exist for two weeks after the disposal date. Pages can be co-edited by friends and colleagues, much like a wiki. There's a history of revisions, a rich text editor, and bookmarking.
Creating a page is quite simple—no registration is needed. Simply enter a title and the captcha code; next bookmark your page and set your master key. Edit from there. Breathtakingly easy stuff.

"Disposable Web Page is now here! You can create a disposable web page with as little effort as a few key strokes and start right away at filling up the page with the content you want.
Disposable web page offers you the convenience and freedom of getting information out there on the internet with as little hassle as can be."

This is certainly an interesting concept. I imagine it could be used for countdowns to birthdays, vacation, or for personal challenges. Seems really simple to use.

Is there a market for this? Will people know what to do with a disposable web page?
