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.
