Is there a site where you can list+propose fun activities you want to do and friends can view & vote on them?

I feel like there must be something like this already. For example:

  Short term: Check out Outside Lands this weekend!
  Medium term: I want to camp in Yosemite
  Long term: Go to the Cannes Film Festival!
