Another way to support your spiritual reflection and/or practice thanks to g+ is to join communities.
Large communities related to Buddhism are worthy of interest, e.g.:
• "Buddhism and Meditation" (37,194 members),
• "Zen Buddhism" (2,595 members),
• "Secular Buddhist" (781 members),
• "Buddhism Q&A" (288 members),
Please pay attention to the differences in guidelines of each community. Despite its size, "Buddhism and Meditation" has a very high "average quality of content", thanks to strong guidelines and an excellent team of moderators. If you join the "Buddhism and Meditation" community (of which I am currently the lead moderator, although Jason Decker is to be credited for the creation and early management of the community), the guidelines are at plus.google.com/106651989741536097256/posts/79kAQcQpc9L
Moreover, attached to this post is a small circle of people regularly publishing original posts on Buddhism on g+ (not necessarily just on Buddhism though).
I think one of the mistakes teachers in general easily make is to think that one's particular view (and/or school) is 'right', or is 'better' than another…
While this might sometimes be justified in relation to a specific context, often it is just 'ignorance' creeping back in, the re-introduction of arbitrary duality and of contextless generalities hiding prejudices.
Promoting others is a manifestation of selflessness (at least when the said others are 'independent', and 'competing' for the same followers / students / supporters…). I teach selflessness, so here is one practical embodiment of the teachings! "Walk the talk" as they say!
There are many more people on g+ with high-quality posts related to Buddhism (quotes and book excerpts; links to websites, articles or videos; reshares…); but the point of this circle is to propose people who regularly create their own new content.
They come from various traditions and backgrounds, and I don't always share all their views, but they surely provide many seeds for Buddhism to flourish on g+.
