http://superviva.comIt's a site that allows you to create and manage a list of things you want to do with your life. But the really cool thing is that you can browse the lists and ideas that other users have entered.
There are
niche ideas galore within those lists:
Go whale watching
See the aurora borealis
Visit Scotland
Learn to belly dance
Of course, there's a lot of rubbish too, from the hilarious to the downright sad:
Blindly pick a place on a map and visit it
Positively affect the lives of a billion people
Finally get that triflin' b***h to LEAVE ME ALONE
Check it out, I guarantee you'll come away with an idea for something!
