Should archive team get on this?
On the one hand, this absolutely is a time capsule. It's hard to get something this real and authentic. It is a legitimate snapshot of 2009 - 2012 and probably has no like anywhere else in the world.
On the other hand, do these folks even know? Would they be okay with it?
I suspect Google might close this if it gets enough eyeballs.
I think Archive Team should archive these. It's a fleeting glimpse at a disappearing world, where smartphones were brand new. We won't be able to recover it if it's lost.
