IPFS Pics
My concern with the IPFS claims of permanence, like "Where you can know for sure your pictures will be available forever" is that, AFAICT, files are only uploaded to the network once another party requests them.<p>An example:<p><pre><code>  $ipfs init
  $echo 'agdkjagka' > test
  $ipfs add test
  added QmTtmsSSTH5fMQ9fn9NRXWtcZXnBBazxR8fidXcE5KB76h test
  $rm -R ~/.ipfs
  $ipfs init
  $ipfs cat QmTtmsSSTH5fMQ9fn9NRXWtcZXnBBazxR8fidXcE5KB76h
  Error: merkledag: not found

</code></pre>
In English, `ipfs add` does not upload anything to the network. The only way a hash becomes distributed on the network is for another party to request that hash. Even then, I believe that the data only exists on that party's system. That is, if both you and the requester leave the network, the data is gone.
