LastWishes.com will e-mail your last messages to friends and family.

Since it was launched last October, the site has drawn more than 10,000 customers who've paid initial fees of at least $39.99 and agreed to annual fees from now till doomsday, all to get in the last word by text, photos and videos for their loved (and maybe not-so-loved) ones.
Why can't I come up with something as clever as this? First I read about 19 yr old who successfully started mobiletracker.net making 55K annually in advertising. Next I'm surprised by LastWishes.com's 10,000 paying customers. Looks like I just need a good idea and a little luck.
