Google+ has been doing this for quite some time. The improvements are generally acceptable. The fatal flaw for Facebook though is their insane compression of uploaded photos.
No one is asking too much when they ask for full resolution1.
- I understand in a mobile first world, full resolution on 13MP phones might be tough to swallow, either on Facebook’s end (storage, bandwidth, etc), or on their consumer’s end (mobile latency, download speed), but Google+ handles it without flinching. ↩
