There was a YC company in W12 called Grouper that basically implemented all of the grab-bag of ideas. It was a 3-on-3 blind date at a pre-determined spot. Each person had to pitch in $20 to participate, which meant $120 revenue for each date. It seemed to be going well - I wonder what happened to them.
Recently went to an open house in Hayes Valley. Asking price 2.595 million. Checked back with a real estate agent later, and got these stats: There were 6 offers, 5 of which were all cash. The winning offer was for 3.3 million.

That instagram screenshot clearly shows that the transmission is over https, which means that the whole "susceptible to would-be interceptors" thing invalid. That is, unless you're under attack by a man-in-the-middle proxy. If this is the case, then you have bigger issues on your hands. The foodspotting screenshot is over plain http, though, so it IS susceptible to a normal eavesdropping attack.
