A partnership like this makes quite a bit of sense.
I might build an excellent interface to IA's millions of images, so good that it becomes the default way of viewing them. Countless bookmarks and links from other sites are published against the material through my site. But then one day I decide it's just not working out anymore and I pack it all up. I call this imaginary system Fleckr.
I'm not saying people shouldn't build what they want in this way, but IA shouldn't rely on other services to host anything that it wants to stick around. They appear to have done that with Flickr, because Flickr had a good system, but now it's all dust. Or, if not dust, it will require a complete system to be built to do something similar, migrating user contributions (if they were salvageable) to this new system. I'm saying this new system should be owned & operated by IA. Building it w/ volunteer work under a FOSS license like many other large projects seems a reasonable option.
My guess is that the conversation was initiated by Flickr. Whether IA agreed with them from the beginning or was forced to "agree" probably doesn't matter, especially because I can see the merit of the argument that Flickr may not be an appropriate platform. I'm just hoping things were save in a way that they'll be able to implement a replacement at some point.
what isnt clear to me is the survival of the content, was there a data migration or was it all just nerfed?
What's been lost is the efforts of all the users to separate the interesting images from the chaff.. and organise them into collections. For such a large corpus that's a really valuable thing.
Also links people had to those images are just dead.
And all the images users had previously favourited have just disappeared from their collections.
It's an interesting challenge with IA because they have > 100 petabytes of content, many thousands of $ in hard drives alone. Too much for random individuals to decide they want to host their own clone & become a mirror. So, we're be looking at large institutions or companies to do this philanthropically. Or, here's the tech challenge, some distributed mechanism where participants all host a portion, with enough redundancy that a large % could go offline and still keep integrity.
