I signed up to try it out. I actually think the convenience could be a huge win. I already see lots of potential in the UI. Some thoughts I had: 1. Bridging the gap between digital and analog is not a bad strategy if you can bring all the advantages of digital along with it. 2. Already their UI lets you queue up letters to send, schedule letters for particular days, save drafts, etc. 3. It could track more metadata in the digital world, i.e. all sorts of other mechanisms like custom fields/notes to help you track these against customer problem numbers or account numbers at a business. Automatically support using a Google Doc, etc. 4. I suppose an API to tie it into your own applications could be pretty nifty. Especially if they get to the point of allowing businesses to get more bulk mailing options that are much cheaper than $1 a letter. 5. As I mentioned earlier, add support for a community of user-generated content of greeting cards that can be voted/upvoted, 6. Add support for viral/political/consumerist letter templates that can be shared/embedded. Provide a link and let people pile onto a letter-writing campaign. It might look like astroturf, but could allow people to at least scribble an electronic signature. Lots of potential here. Just need to follow through. I'll see how my first letter looks.
