I’m not sure why, but I remember as a kid reading through the classifieds and finding a section of "ads" from people who had met each other randomly but didn’t really exchange contact information. They would put up an ad and hope the other person would read it and remember the event.
The Blinka.me website is attempting to take that whole "reconnect" effort and webify it with some good ol’ Web 2.0 charm.
Combining the simple idea of the classified ad, with the power of the Internet, GPS, mapping and social media should make those efforts pay off in a significantly higher rate of return for individuals.
The Blinka.me website is a little more pro-active with their efforts though. With Blinka.me, when you meet that guy or girl at the supermarket and have a nice, unexpected conversation, just tell them "Blinka Me" later. Then you can list the event on Blinka.me with the date and a bit about the interaction that will make it unique. The other person will come to the site and "look for you".
You can then follow-up on the conversation and learn more about each other, but still without sharing any real personal contact information or data. After you decide both of you are normal and not a psycho axe-murderer or the type of girl that boils a rabbit in your kitchen, you can pursue the relationship a little further.
