This is more of a heads up but here’s an email I got from Dropbox;

Dropbox:

Hi Robb,

We wanted to let our developers know about an upcoming change to the Public folder for all user accounts. In April, we launched the ability to share any file or folder in your Dropbox with a simple link. This new sharing mechanism is a more generalized, scalable way to support many of the same use cases as the Public folder.

After July 31, we will no longer create Public folders in any new Dropbox accounts. If your app depends on Public folders, we recommend switching to the /shares API call. Public folders in existing accounts, however, will continue to function as before.

Please email us at api-program@dropbox.com if you have any questions or concerns.

So, it looks like if you don’t have a dropbox account yet you may want to get one if you want the public folder that Anki currently uses. Anki may update to the shares format or dropbox may rid itself of public folders all together at some point. Either way it looks like things are changing in their current relationship and it may be worth getting an account ‘just in case’.
