Google+ Sparks was a kind of RSS/StumbleUpon thing. Flopped.
Reader sharing became sharing into Google+. Many in the Reader crew defiantly cried out against it and said they wouldn't share things if they had to use Google+ to do it.
It wouldn't have been all roses no matter how you cut it.
I think people are in the bargaining phase of dealing with their post-Reader era grief.
Google, Facebook, and Twitter don't want publishers to use RSS/Atom. They want them to publish using their respective, proprietary APIs.
The blogpost at http://googledevelopers.blogspot.co.uk/2013/07/pubsubhubbub-... also mentions a Feed API.
I'm confused, I guess this means that only the sync + ui for reader is dead.
So, what?
> PubSubHubbub was very much part of a different era.
PubSubHubbub is very much part of now, which is why they just released a new version of the spec.
