Mobile Photo Sharing Apps

It looks like as smart-phones become more photo capable, photo sharing apps will become more popular. Instagram, the app we talked about in last class, now has 2 million members. This Mashable article talks about Instagram and Picplz and how business might come to use them. Picplz allows users to comment, analyze and like each photo, while Instagram relies on hashtags to organize pictures. Starbucks is the first major brand to join Instagram and about 1000 pictures are marked with their hashtag. I have an iphone 3 and its not too great with loading pictures, so I haven't use my instagram app too much. Will picture sharing and viewing become another way to pass time on your smartphone?
