Hopefully, it should have been like that from the start.
Yip. We have all these share functions but they are far too reliant on other social services.
I'd argue that sharing on the PS4 is easier than it is on the Xbox One, but the sheer ease of being able to access videos and screenshots via websites suck as xboxclips and xboxdvr etc makes it a lot better. I don't think that this is exactly what this is but it may be a step in the right direction as right now I don't even bother with the activity feed.
