ironically, the blog lacks a rel=me link that would make streetpass work on it :)

Oops, added. Thanks :)

Surely the blog post itself comes before the social post linking to the blog post. The blog post is the source.

Obviously;

"Eugene" [1] boosted the post, which is how it gained attention i believe. That's what i meant with "source" ;-)
