A recently discovered web site along the lines of PostSecret and GroupHug (both of which I liked when I first saw them, although I really only read PostSecret nowadays) is JoeApology.Com, which is

"a site where people can freely and anonymously post their apologies. Think of it as a confessional of sorts (without the religious ties, that is). Are you feeling sorry about something you did? Do you want to get something off your chest? Go on, tell me about it...and remember, it's completely anonymous. Just post your apology, no matter how big or small, and you'll feel so much better. I promise."

Some, as you'd expect, are trite and melodramatic (as are some posts in my blog, seeing as we're all consumed by our self-importance) but there are some nice ones as well, such as this one:

Dear Pringles (my cat),

Sorry I don't have enough time sometimes to let you into the hallway. I know you love to walk around and sniff the stairs and the neighbor's door.
