Yahoo has worked hard to turn Flickr back into a social image sharing threat again. The most recent Flickr 3.0 apps are beautiful, feature rich, and after June 30th, you’ll need to have a Yahoo account to access them.
In Yahoo’s attempt to push their own usernames (gathering user data & insights in the process) Flickr is the newest product that will be adhering to the log-in directive. The first implementation of the all Yahoo usernames occurred with the ever popular Pick’Em NCAA college app back in March. Flickr currently supports Yahoo, Google and Facebook logins.
While this should be a boon to Yahoo user creations, it very well may hurt the Flickr use (especially with the apps). The current apps feature the Faebook/Google logins on the home screen and those users that rely on these other accounts will now have to create their own Yahoo username.
Flickr Users will be able to login with their Facebook and Google accounts through the end of the month.
