I just wrote a blogpost about what it's like to be the First User of a product.
That's what I'm doing here. Using the product to solve a problem it was intended to solve. In this case, the purpose is one of a myriad of variants on the same theme. A web site with the usual components, but arranged in a specific way to accomplish a specific purpose.
The posts here are shorter than a blogpost but longer than a tweet. And what comes back is the purpose of the message. How they are arranged isn't important.
