Back in June, Google rolled changes to scraps on orkut; orkut now allows you "to choose to send a private scrap to a friend. On the new orkut, before posting a scrap, just change its visibility to "private", and that scrap will remain visible only to you and the person receiving scrap. If you don't change default options, your scraps will have exactly same behavior as before, so there's nothing to worry about, things only change if that's what you want.
Every scrap (as well as photos, videos, etc) will now have a privacy label, so you can easily tell who else can see it. These are exactly the same as the privacy levels that we already had on photos: private, friends and public," informs Google.
