I had a feeling this would happen ... and I would love to see the usage logs for the instagram app over the last few days. I can say from an anecdotal perspective that my personal instagram dashboard was very lean. For the time being I am going to continue to focus my photo sharing energy on flickr and the new iOS app they released. If the folks at flickr really wanted to win they'd release something that is universal and works just as perfectly on the iPad as it does on my iPhone.
The concerns we heard about from you the most focused on advertising, and what our changes might mean for you and your photos. There was confusion and real concern about what our possible advertising products could look like and how they would work.Because of the feedback we have heard from you, we are reverting this advertising section to the original version that has been in effect since we launched the service in October 2010.
