One of my fave websites recently has been Letters of Note, edited by Shaun Usher of the UK. The site collects interesting and forgotten letters sent to celebs and not-so-popular figures.
For instance, there's the letter Christopher Reeve (of Superman fame) sent to a classroom requesting his photograph. It's touching and powerful, since he wrote the letter after his paralyzing injury.
A note from Charles Bukowski rips apart censorship of his book, while another from Walt Disney urges a friend to stick with him to form the Walt Disney company.
Sometimes, the letters are from unknown people, such as this discovered letter from someone with an "amusing letter of complaint to the Sahibganj divisional railway office in West Bengal."
The letters are reprinted as .jpegs and transcripts follow the pics in case the writing isn't legible.
Letters of Note is a fascinating glimpse into forgotten lives and small corners of humanity, much like PostSecret and its anonymous postcards. But here we see the faces behind these poignant sentiments, however quickly composed.
The site also acts as a nostalgic trip to an era when people actually wrote letters to each other, their character expressed through their calligraphy. Twitter, this is not.
