The ability to subscribe to a specific tag on the Instagram platform facilitates the curated aggregation of content. For instance, a user interested in photography could opt to receive posts tagged with “#landscapephotography” directly in their feed, alongside content from followed accounts.
This functionality is valuable for discovering content related to niche interests, staying abreast of trends, and monitoring discussions around specific topics. Prior to the introduction of this feature, users relied on manual searches or third-party tools to track content associated with a given tag.
