Instagram began as a mobile-only service, but now it’s enhancing its web version so you can use the service without opening your phone. Today Instagram rolled out an Activity tab on web that’s identical to the notifications tab inside its app. Here you’ll be able to see who Liked or commented on your posts, or who followed you or tagged you. It’s now available to all users.
Instagram declined to comment regarding whether this was part of a bigger push on the web, so this seems like more of a one-off feature addition. But making Instagram more cross-platform enhances its ubiquity and network effect. That could grow its moat and make sure no other service usurps it as the hot permanent photo sharing app.
