Hi Flickr User,
In two weeks, Flickr will remove the option to sign in with a Facebook or Google account. Instead, you will need to sign in using a Yahoo account. To create your Yahoo account click "get started" below.
We want to make this transition as easy as possible. If you have any questions, please check out our Help Articles or come see us in the Help Forum. We appreciate your understanding during this transition. Thank you for being a part of the Flickr community!
Though the notice gives no justification for this move, the motivation is obvious enough — people love Gmail and Facebook but are largely ambiguous about Yahoo! which probably results in a weakened userbase in a situation where people are able to fully use their services without having an account. However, a cursory search of the Flickr blog on the topic does not yield obvious results.The move also increases the likelihood that users will then go on to make use of other Yahoo! "services."
I guess it's not enough to undermine open content licensing, now you're going to wall your garden.
What alternative to Flickr are you presently using and what alternatives do you think deserve more attention than this aging also-ran?
