Yahoo's Openness To Search

Yahoo announced that they have integrated a couple of applications from their Citysearch and Yelp and its own
Yahoo also gave a shout out to some other apps on display at the Infobar for TV.com, and in terms of market share right now, it's going to be hard to play catch-up. I'd say this is a step in the right direction either way.

Implementing SearchMonkey features on their own for wide use by the average Yahoo user shows that they're willing to do so with good apps. This should provide developers with encouragement for building more creative and useful ones now that they know it's possible to get them to become part of normal Yahoo search results. And the more inventive and creative ways to bring relevancy to results that are created, the more reasons there will be to use the search engine. They've still got some hurdles to jump though. Do you think this is a significant step for Yahoo?
