Point 1 is true for me as well. But I take a different approach in doing Point 2. Since everyone has a gmail account (at least my target audience) and hardly have any activity on G+, I created a G+ community with just the right people and post updates there. These updates automatically send notifications via email to the community members. The way content is organized and presented in a community is much better than email IMO. Of course everything can be translated to email - comments can be reply with text and likes/+1s can be reply with +1 - but looking back, it is a much better user experience to do this in a community/group rather than email.
