Lead to wallet being returned by a person who works at the biopark in Potrero, and my passport by a person who worked in stem-cell research at Byers Hall of UCSF.

Fucking AWESOME.
Still, very very cool.
If this guy had been anonymous and unknown I doubt we'd have seen the same result. This also has nothing to do with google+ beyond it being the platform for discussion used, the post could easily replace "google+" with any online discussion platform, hackernews for example.
