Although Instagram is a huge global community and you can link to your photos online, it's essentially just a mobile application, so there isn't a dedicated web app for browsing photos, following people and tagging your images.
However, over the past year a number of web apps have popped up which bring you some of the mobile app functionality to your web browser.
To celebrate Instagram week we're running an easy to enter mobile photography competition with our friends at Orbitsound. All you have to do is take a photo with an Autumnal theme and share it on Twitter along with the hash tag #ShinyAutumn. It can be of a leaf or a Halloween costume, we really don't mind. The winner will get a fabulous T12v3 speaker bar from Orbitsound and 19 runners up will get random iPhone related goodies.

Webstagram is one of the most popular web-based Instagram apps with lots of options, like viewing your feed, browsing random images and follow buttons. One of the things I like most about the app is it tells you which filters your friends have been using, which is great if you need some inspiration and want to recreate certain looks. You also get your own Webstagram URL, so if you want to share your images with people who don't have the Instagram app, this is an ideal way to do that. http://web.stagram.com
