I heard about this somewhere, but never checked it out further, so thanks for posting, Blue!
I'm still thinking and will go back to look more, but perhaps part of the appeal is that nearly everyone can find at least one of their own thoughts in there...with some of them, it's uncomfortable and cathartic at the same time. It seems we're all so focused on being "normal" and perfect that it's comforting to know everyone's just human and basically has the same quirks, experiences, thoughts and secrets.
Wow, Blue - that's a really powerful site. Many of the postcards echo my own thoughts, and it's an interesting way to see them displayed. Thanks for sharing the site with us.
edited to add: I think I want to make a few postcards of my own, now...
