From the Twitter Engineering blog:
While on vacation in Germany, Michael Busch, one of our search engineers, implemented a demo of image and video search. A few weeks later, during Twitter's first Hack Week, the search team, along with some members of other teams, completed the first demo of our new search experience. Feedback from the company was so positive that the demo became part of our product roadmap.
Impressive. But it reminds me of this CNN article I saw the other day, Why is America the 'no-vacation nation’?, which starts with this line:
Let's be blunt: If you like to take lots of vacation, the United States is not the place to work.
I think this all started when I brought my sleeping bag into work one day back in 1999. Depressing.
