Instagram allows adding @ and # in your profile as clickable links

In its official blog, Instagram recently announced new additions to users to express themselves more in profile, using the @ and # signs.

The idea is simply that when you add @ or # in your profile, they will be classified as links where you can place your interests and things you like or care about. Instagram will start adopting these tags as links that are clicked and accessed. Directly.

When you put someone's account on your file, they'll receive a notification so they can remove the link to their profile so that the account remains in your file but without links.

On the other hand, Instagram supports the QR Code feature within the application, which means that you can add anyone via the code as soon as it is on SnapeChat and Twitter now.
