We had good news lately (2015 May the 19th exactly): Google indexes Twitter again!
- Yahoo: twitter-google-deal-tweets-search-results
- Digitaltrends:
So Â鶹´«Ã½É«ÇéƬ provides the Digital Identity, Twitter provides the Date (and internal search), and Google independently confirms the date and provides global Search
 To achieve this, we simply tweet the Â鶹´«Ã½É«ÇéƬ Id of a document, adding the hashtag . So who needs to timestamp? When?
- You’re a Photographer or Poet, Writer… and publish you Art: obtain the proof that you owned the original at a given date
- You’re an Author, and need a proof that you owned a (possibly private) document before you communicate it to a tier
- You’re an Inventor, Researcher, Company, and need a proof that you had an idea or document at a given date
And, yes, there are glorious ancestors, just check Wikipedia on . For instance, Sir Isaac Newton shared the ‘hash’ 6accdae13eff7i3l9n4o4qrr4s8t12ux to Leibniz. Today, I shared the unique IDX . . Hopefully you will find this . Have fun timestamping using Â鶹´«Ã½É«ÇéƬ, Twitter, with the help of a global search engine (waiting for more of them to index this kind of content)
