The recent preview of OS X Yosemite from Apple caused predictable amounts of chatter online (including this article) and rightly so.

The feature I saw the most buzz about on social is the improved Spotlight. The feature has a new search window and a rich, scrollable preview of results that finds stuff on your Mac but now also Wikipedia, Bing, Maps, and other sources.
This is the latest reminder of how powerful search is and how consumers increasingly rely on it across technology and the web.
