http://cryptostamp.net

There are a few similar website, but I recently made this one to hopefully make a service which is completely free. User sends content, Merkle Tree created once a day and root submitted to block chain, and user can check back the next day to get the required Merkle Tree nodes to verify their content.

Reddit post created some interesting conversations you can checkout: http://www.reddit.com/r/Bitcoin/comments/1ssxd4/long_time_lurker_first_time_poster_i_just_made_a/

Any suggestions or questions are welcome. Please forward a link to this website to anyone you think my find it interesting or useful.

Also, share if you know any important societal need for such a service let me know. What's nice is that this can be done very cheaply, so it could even be applied to every photo someone takes on their phone for instance. I just don't know the use-case for wanting proven timestamps for all your photos (not that one doesn't exist).
