Instagram's photographic social feed isn't as novel as it once was, and you may be tempted to stop using it if you're overwhelmed by that never-ending stream of square pictures. How is the company supposed to keep you coming back for more? Though regular email blasts, apparently. TechCrunch has confirmed that Instagram is now sending "Highlights," email digests that showcase some of the better photos from those you follow. While this see-what-you're-missing strategy isn't new (Facebook and Twitter have done this for a while), it acknowledges that only some of Instagram's 300 million users are active shutterbugs -- this could help you remember the service and catch photos that would otherwise slip under the radar. Yes, the highlights are ultimately meant to get you viewing more ads, but they may be useful if you'd rather not spend every day wading through an image stream.
