Instagram has answered our prayers. It's finally introducing threaded replies into its app. Now you'll be able to see comment threads within the app. If you have friends and followers who like to interact with you a lot, it gets confusing to follow conversations before because even when you hit Reply to a comment it just tags the user you're talking to but the comments just appear chronologically. Version 24 of Instagram will group replies underneath each thread and when there are multiple replies already, you'll just see how many have replied first before you see the full conversation. Facebook has adopted this approach before so it's about time it made its way to Instagram. The feature is rolling out globally in the coming weeks to both Android and iOS users.
