Can you have a publically editable layer that does not require the user to log-in

I am setting up a public web app to embed into a web page. Is it possible to have a "crowd source" layer in the app that members of the public can mark up - without it being through Twitter?

If this isn't possible through AGOL, but can be done via AG for Javascript or Flex, please let me know.
