Photo-oriented social network may allow you to follow hashtags.
Instagram may soon introduce the ability to follow hashtags. Currently, you can only follow individual accounts and see their posts in your feed. If the company decides to add this feature, it will be more easier for you to find content based on your interests.

For example, you will be able to follow the hashtag #shotonmyiphone to see in your feed photos captured by users with iPhones, without having to actually follow all these users. This could be a very useful addition to Instagram if you want to follow some niche topics. However, following too many hashtags may be overwhelming, and that’s why the hashtag posts may be limited to top posts.
