Several days ago Jack Dorsey, creator and co-founder of Twitter, started tweeting about the very early days of Twitter (or as Jack says, Twttr for short). He spoke about the days when Twitter was being developed under Odeo’s roof and the team working on the product was no more than 4 people.

As Jack shared more about Twitter’s youth, including sharing one the earliest sketches he made in a notebook, you couldn’t help but get the feeling that nobody knew how big the idea they were working on would become. While many of us may see Twitter as a wildly active website with hundreds of millions of users, involved in national uprisings and the sharing of the inital photos of large natural disasters, the sketches and sharing of the development story remind you that everything which exists on the Internet today once came from nothing more than crooked lines on a piece of paper.

Moreover, imagine being told 5 years ago that people would be “Tweeting” in the millions, as many as 6,939 per second at it’s current highest. Re-Tweeting even. You’d probably had laughed at them. You’d definitely had never believed them. With Twitter now being valued at least at $3 billion, there’s no doubt that they’ve become something valuable to many, many people.

There’s nothing I love more than people press forward with an idea, as strange or useless as it may be in the eyes of some other people, only to have it explode into something nobody could have seen coming. Now if only Twitter had it’s own movie (I’m sure as with The Social Network, they could make it dramatic enough to be interesting).
