From their announcement it sounds like you might not notice them too much. It won’t be some crazy “take over your screen mid sentence” type of advert. Instagram also mentions that you will have some control over it all by allowing you to hide ads. However, they also mention they will ask for your feedback on what didn’t feel right and why you hid it.
So be on the lookout if you are a big Instagramer and let us know your thoughts on the matter.
