I'm a sucker for Postsecret, which has to be why I like Draw Secret so much. This site is just like Postsecret, except that instead of sending in a postcard, you send in a picture drawn on MS Paint or Mac Paintbrush.
I never felt artistic or secretive enough to contribute a secret to Postsecret. Draw Secret seems right up my alley though. Paint is not a tough program to use, and Draw Secret welcomes any and all comers. Warning: the secrets are still heartbreaking. The art, not so much.
