In our technologically savvy world where we document maybe too much of our lives, a daily reminder of what we were up to a year ago sounds like a great way to recall the past.

PastPosts is an interesting new Facebook application created by techie specialists, Benny Wong, Jonathan Wegener and Matt Raoul.

It’s quite simple. Connect the app to Facebook and every day you get a new email showing you your wall posts from that day the year before. If you didn’t use Facebook that day, you get no email.

This app really is a great example of how much of a digital trail of data we all leave behind using our various social media.

It has the potential to be fun, interesting, embarrassing, etc. etc. The list could go on.

My curiosity is going to choose interesting and give it a try. How about you?

Go to pastposts.com if you’d like to try.

Do note that this application asks for access to a lot of your Facebook information. Those who are uncomfortable with this should not use this application.

You have the option of removing access to some of the aspects of it (such as Posting to your wall) through your Privacy settings after you have added the app.

Go to Account>Privacy Settings>Apps and Websites>Edit Your Settings>Select the app and remove what you wish. Unfortunately, it still needs access to your most basic information.
