Flickr Adds Hashtags to iOS App

Flickr released an update to its iOS app on Saturday, adding hashtag support to the photo-sharing service's mobile platform

While Flickr has long used a tagging system to categorize pictures on the web, the term "tags" has been renamed to follow the ever-popular trend of hashtags. The app also introduced #FlickrFriday, where adding the hashtag let the user instantly participate in Flickr's weekly photo challenge

Much like Instagram, clicking a hashtag will take you to search results of relevant tagged photos. The addition is the latest in a series of changes after the company's integration with Twitter at the end of 2012. Other updates similar to Instagram included usernames using the @ symbol and retro-style filters
