Douglas Bowman, the top visual designer at Google, recently left to lead the design team at Twitter. Bowman shares the dynamics of Google’s data driven design – one small change to a link color on Google.com can affect the bottom line in large dollar amounts.

At Twitter, Bowman will have the toughest job as an interface designer. He now has millions of critics to comment instantly on his design implementations. This is the future of all websites, thus the need for a strong balance and philosophy on utilizing customer feedback for design and application direction.

I also take Bowman moving to Twitter as yet another indication that search is evolving. Search.twitter.com is a great search tool, a bit coarse and sometimes distorted, but the best resource for live search. Mahalo.com is also a good resource for social search, more refined in the vein of Wikipedia. And finally, for shopping,  Scour.com will pay you to search and provide discounts for purchasing.

The NY Times calls this the Age of Google. Twitter is not the next Google, but Google is nearing the end of its Age. Search is young and entering a new era.

Just read this great e-mail from Joel Ordesky on the Do’s and Don’ts of Social Networking. Social communities have their own culture and it’s important to learn the etiqutte before entering. The more we live in this online space, we create our own language and sometime’s ‘regional’ dialect. Twitter probably has the biggest learning curve as there are subtleties within the technology and often a shorthand language to fit within 140 characters. He recommends The Ultimate Social Media Etiquette Handbook which could be a good read, especially if you’re introducing an organization to social media. Joel also links to Brian Solis’s thoughts on Finding the Tweet Spot – Top Tips for Building Twitter Relationships – a very good read. Learn the Do’s and Don’ts of Social Networking.
