Instagram has had no shame in copying Snapchat's most popular features, and now, it appears Instagram is after Pinterest as well. Recipes, fitness tips, design inspiration, and DIY how-tos are already popular on Instagram - and now, users can save their favorite posts and organize them into "collections."
To save an image to a collection, long-press the bookmark icon
Collections are private to users
Pinterest's differentiating value is website traffic. Currently, Instagram collections are private and most accounts are unable to link to a website. Instagram reported that 46% of their users have already bookmarked at least one post - we're betting that if collections become widely used, Instagram will continue to iterate, allowing collections to be made public and/or letting every day users link off of the platform.
