Hashtags are the organizational backbone of Instagram, putting the world of #InstaGood and other delights at your fingertips.
While you could always search Instagram by hashtags, or click through on one to see other images with the same tag, the social network is now letting you follow hashtags as you would a regular Instagram account. #Hooray.
To get started, search for a hashtag or tap on one from any post, which will bring you to the hashtag page. From there, just hit the follow button. Images with that hashtag will then be populated into your feed in the same algorithmically massaged manner as the rest of Instagram’s posts.
If you have a public Instagram account, the hashtags you follow will be publicly visible. #ChooseWisely.
