Instagram [3] has polished up [4] photo displays on mobile web browsers. On the new Instagram web pages, you can comment on and "like" photos while in a browser like Safari or Chrome, without moving to the Instagram app. Directions to the app view are well marked, though, with an un-missable "Open in app" button appearing on the top right corner of the screen.

Instagram's early days were app-focused, spawning a clutch of third-party web-viewing apps [5]. It wasn't until June this year [6] that Instagram spruced up its web photos with interactive commenting and "like" buttons. If you followed Mark Zuckerberg's ringing endorsement of native apps [7] at TechCrunch Disrupt recently, the web move might come as a bit of a surprise. More so since it's been just a month since Instagram revamped its mobile app [8] with nifty location integration and Photo Maps.
