Instagram announced the change in a blog post, but initially didn't explain its intentions. The updated terms suggests that Facebook wants to integrate Instagram into its ad-serving system, which can, for instance, promote an item by telling users that their friends "Like" it. This is fairly similar to smihuv Facebook's current ad-serving system. The new terms make it clearer that Instagram could use your photos to market to friends instead of a business.

However, yesterday, Instagram announced that it was miscommunication. They actually just wanted to experiment different aspects of advertisements.

Dodged a bullet there, Mark Zuckerburg. Facebook seems to have dodged a lot recently.

All in all, users are upset. So upset, that many similar photo sharing apps like the "flickr" app are receiving huge amounts of downloads within the last few days. But as everyone should know, posting pictures and information on the web believing it is private, is well, ignorant.
