In a move that should surprise absolutely no one, Instagram announced today that users may browse their feed from the social network’s website. All users need to do is go to Instagram.com and login with their account credentials.

Much like the iPhone app, users can browse through recent photos, like photos by double clicking or pressing the like button, and comment.

The one thing users can’t do is upload pictures to Instagram from the website. In a blog post, Instagram co-founder Kevin Systrom explained why:

We believe that you should be able to access Instagram on a variety of different devices, any of which may be convenient to you at a given moment – including your desktop computer or tablet. We do not offer the ability to upload from the web as Instagram is about producing photos on the go, in the real world, in realtime. On the other hand, Instagram for the web is focused on making the browsing experience a fast, simple and enjoyable one.

Late last year, Instagram began to carve out a Web presence by rolling out profile pages of users. The social networking service, which started out as a simple iPhone app, was purchased by Facebook almost a year ago.

If you’re wondering why Instagram is doing this, I have a simple answer: advertising money. A Facebook vice president admitted in December that the company will find a way to “monetize” the service. And I suspect the new Web feed will be full of ads shortly.
