Instagram adds hashtags, brands already love them
Each tag even has its own RSS feed that you can subscribe to, if you wish -- these are available by replacing "yourhashtag" from the following URL with the name of the tag you want to follow: http://instagr.am/tags/yourhashtag/feed/recent.rss
Basically, an Instagram hashtag is much like a photo album, only anyone can easily add pictures to it. And brands seem to love the new functionality. Instagram has partnered with Charity: Water, Brisk Iced Tea, NPR, and many others, who have already launched their own hashtag campaigns. For example, Charity:Water is asking Instagram users to tag pictures of water in their life by using #charitywater. In the future, expect many more brands to hop on this bandwagon, since it provides them with a very cheap way to promote themselves and their offerings.
