i actually like this feature. if you want to share a certain file in a folder, there is no need to move that file into the 'Public' folder. thus orphaning it from the rest of the items in the original folder.
agreed, no big deal but it's an oft requested feature and quite convenient too.

That has been possible for ages with Gdocs. You just email people with a sharing link to the document, and the link can give anyone who has it read access, or write access, if you stipulate that.
At any time, you can revert the file to non-shared/"private" status, and thus remove further read/write access to the file at that point - thus rendering the sharing link obsolete.

i know about that feature, but Gdocs emphasises on documents but Dropbox is more on general storage. that is why i like it even more in Dropbox because my sharing is not limited to documents..
