I finally found the feed for Alan Reiter's Cameraphonereport. Definitely thumbs up. Each post is more in depth than in any other weblog I'm subscribed to. E.g. this discussion of photo albums and cameraphones.
Jump on it if you have the spare cycles.
Personally, I think photo album types should add whiizzy non-photorealistic rendering tools for photo manipulation. The hard nut? Making the tools workable from handheld devices or non-desktop interaction in general.
