Two days ago, Instagram released their own version of a web app, or as they to call it Instagram Web Profile.
With a user interface similar to Facebook, users and
stalkers followers won't encounter difficulties in using the Instagram web app. It's also a great way to showcase your iPhoneography to your friends and family who doesn't have the Instagram app in their phones.
I personally like the convenience of answering comments in my photos. However, users cannot use this web app to browse their friend's feed, unless you know their username then you go directly to their Instagram web profiles.
