Twitter: Past, Present, and Future

To visualize the future of Twitter, one need only examine the lessons of history. A part of its inception, Dom Sagolla tells the story of Twitter’s humble beginnings and the lessons learned along the way.

A compelling vision for the future of short messaging concludes this talk, influenced by experience traveling across the US and abroad in recent months in support of Dom’s book “140 Characters: A Style Guide for the Short Form.”

Snowboarding

Hitting the slopes of Park City with the folks from Tweet House. You’re welcome to join us!

I met Tracy Sheridan at Lunch For Good, where she bought a copy of 140 Characters using Square. It was still in private Alpha then, so when it launched I met her again. This time at Sightglass Coffee & Roastery.

Here’s a clip of us using Square to sell Tracy her second copy of 140 Characters:

We also talked about the beginnings of Twitter, the genesis of the book 140 Characters, and the book iPhone App. Also included are some thoughts on being a Square merchant.

Thanks Tracy for capturing this.

I have been testing Jack and Jim’s new invention Square since April 2009. Jack bought me breakfast, then proceeded to charge me for it, using his iPhone.

I became a Square merchant in May. Since then I’ve been documenting a new 140 character space: the credit card line item.

Right now, I’m one of a handful of active merchants using an Alpha version of this new payment system (including Sightglass, Lilybelle, and Willotoons). I can process credit cards without the need for a merchant’s account to start. I use Square to sell copies of my book 140 Characters: A Style Guide for the Short Form.

Powered by the force of my swipe, the scanner is designed to fit into any smart device (read: Google, Blackberry, etc). Development is planned for the other devices (see Jobs), but the Beta is only for iPhone or iPod touch at the moment.

For more information, sign up for the Square Beta (opening soon to a few more merchants), follow @Square and keep a lookout for @SquareBook.
