Don't forget your digital assets and social network accounts when preparing your estate plan.
You can plan similarly in your estate plan. For example, you can state in your Will that your executor or some other person of your choosing, shall have the power to access, handle, distribute, and dispose of your digital assets, and the power to obtain, access, modify, delete, and control your passwords and other electronic credentials associated with digital devices and digital assets. You can designate this person to announce your death on your Facebook page, to set up a memorial page and to later shut down your Facebook account (or Twitter, etc.)
And don't forget your cloud storage accounts.
