Leaving aside its nefarious URL, 2SquareAnd7YearsAgo is quite a useful application for all those who have become active users of Foursquare. Essentially, this new service can take care of reminding them exactly what they were doing a year ago. Any person who authenticates who he is via Foursquare will begin receiving a daily email detailing where it was that he had checked in one year back to the current date.
The person will get to know his total numbers of check-ins for that day, and the time that each took place at.
What good is this for? Well, 2SquareAnd7YearsAgo obviously has no practical applications at all. Rather, it is a service for those who take their nostalgia seriously. And once new features begin rolling in (such as reminding users not only of where it was they checked in, but also of what was happening in the world around them at that time) it can but become even more meaningful to all those who try it now, and like what it can do.
