Google+ feature request: juxtaposed link posts
Posting links involves throwing spaghetti (and annotations) against a wall and seeing what +1's.
Sometimes, however, it's the dialogue that is as if not more interesting as the data-points themselves. For example, an article about Borders's closing next to a Kindle announcement. And a third about the Google Books deal. I could talk about the three-way links (I'm picturing each link in a triangle with a blurb along the edges) and/or all of them in aggregate.
You've acknowledged the heterogeneity in our social connections. How about the richness in how we connect to content online, the problem you started out with last decade?
