Google+ has been added to the social media at the bottom of each post, as has Linkedin. Though the latter, together with lesser used sites, were moved to a general button, where they appear when moused over.
Please use these to share those posts you find of special interest or particularly helpful. The social media are a major driver of traffic to the site.
Some of our favorites are still not present, but we may have to wait a while for those. Meanwhile, we work with what we have.
Also, it should be noted, there are buttons to share a post by email or to print it out on real-life, dead-tree paper.
