For people who use Instagram for discovering new creators or businesses, keeping track of follows can actually be useful for organizing their interests. You might follow several accounts while researching a topic and then want to revisit those profiles later. Instead of trying to remember every username, a focused service like recently-followed.com can help make recent following activity easier to review. I think the simplicity of concentrating on one specific Instagram task is what makes this type of tool practical.
