I'm contributing to the Modern Letter Project's blog. Each month, participants from around the world get the name and address of another letter writer. Ideally, every month, participants receive a new letter, write a new letter and a response letter.
We're mid project now and the bolg is the electronic extension, a way for all of us to share this experience as it happens. My first post is up today so feel free to check it out and get involved!
We're also photographing sent and received letters and posting to flickr; that's been pretty cool too. http://www.flickr.com/groups/modernletter/
