Lunch started out innocently enough for Snap.com colleagues Brad Haugaard, Joe Chen, Ken Yeh. While discussing Snap's very visually oriented search engine, they collectively wondered, "What about people who don't really care about pictures?"-- from http://www.linuxplanet.com/linuxplanet/reviews/6306/1/
Somebody said, "How about 'visearch'? We could combine a vi editor with a search engine."
The three mused that you could move up and down with the "j" and "k" keys. You might also delete bad listings with "dd" or insert comments into the listing with an "i".
With suggestions from Haugaard and Yeh, Chen programmed a working system over the next few weeks. Chen and Yeh are both software engineers, while Haugaard is a customer service manager.
