Yeah I'm curious/excited about this aspect of Google+ as well, since at this point it's usually someone interesting commenting on something of note. I imagine that soon enough it will be maddeningly clogged with the new equivalent of Farmville! Hahaha... But for now, it can be good and hopefully someday down the road a non-dumbed down type of site/application can be developed to work in conjunction with Google+ to separate the wheat from the chaff, so to speak. As someone who travels alot, I'm interested as well in the notion of the virtual placement of data over a location as well as it being left in position over time. I'm traveling by train to California next month and will be interested to see what others have posted in isolated areas -- say between Sanderson and Alpine, TX.
Are you guys in town for the fair? Is your boyfriend from town? If so, he might know my house from having a huge skateboarding halfpipe in my yard on the West Side from 1990-1996. Of course that was 15 years ago at this point, so I might be over-estimating the memorableness of this if you guys are much younger.
Anyway... Enjoy your visit!
