iPhoto uploads don't show up in PhotoStream
I manually add photos from iPhoto to Photo Stream. Apparently I'm doing this correctly because if I try it twice, I get "All of the selected photos are already in your Photo Stream." But the photos never show up in the Photo Stream, either in iPhoto itself or on my iOS devices. Other photos (e.g. from iOS) do show up in iPhoto.
MacBook Pro, Mac OS X (10.6.6)
