Public cards are a great idea
@chrisanderson, have to have a think how we may make use of them. I've got a separate question on cards that are used as templates for other cards. Is there any way to use a card as the base for a new card without copying the content and clicking new then pasting? It would be a nice feature to be able to open a template and then click a "Create new from card" button and it goes straight into edit mode with all the content of the template but as brand new card. Then the user could populate it, walk through the categorisation and verification steps and just make sure they are appropriate before saving it to their desired collection / board. Am I missing this? Does it exist already?
