In regards to G+, do Google even offer the appropriate APIs to connect? For example, SNAP doesn’t provide direct link. IndieWeb is awesome, but isn’t it still dependent on third party silos. That is why it no longer works with Facebook, right?
I agree with you about the frustration associated with #IndieWeb. However, if there was a simple answer then I think that it would have been implemented by now. I really respect the work being doing at the moment by Chris Aldrich and Greg McVerry, I am also mindful that many of these plugins and approaches are seemingly managed by a handful of individuals. Fine there could be additional documentation, but unless more people are willing to put their hands up (myself included) then it will likely remain this way.
