This is widely linked, but still worth reviewing: How Yahoo Killed Flickr and Lost the Internet.
It’s a common story: successful small company is swallowed and destroyed by a larger, more established firm in a futile effort to extract the value. Stories like this are almost certainly a big reason why Mark Zuckerberg has maintained complete control over Facebook, and will continue to control a simple majority of the voting shares even after the IPO.
Flickr is dying. This kills me, because I’ve got years of photos and annotations there that, I suspect, will eventually need to be migrated elsewhere. That sucks. It sucks even more because it didn’t have to be this way; this is only the endgame because Yahoo has been traditionally run by chuckleheads.
Like you, I have a ton of images on Flickr Pro and know I will need to migrate to a new flavor someday. I’m puzzled as to how this happened. Idiots.
