Wikia Search has announced a new feature called Wikia Intelligent Search Extensions, or WISE, which founder Jimmy Wales likens to "Facebook Apps for search results." The new platform allows third parties to build applications, called WISEApps, that Wikia Search users can enable in their accounts and which add additional functionality to relevant search results (more at our Wikia API profile). For example, the results for an ordinary search for "Chicago weather" will include a link to AccuWeather.com, but if the user enables the AccuWeather.com WISEApp, the search result will include a full graphical five-day weather forecast.
Fancy Hands, virtual assistant service, has launched an API: The Fancy Hands API. The API allows ordinary folks to build apps, add features to existing apps, and build businesses with the power of Fancy Hands' network of assistants. Fancy Hands envisions utilization of the API expanding well beyond the developer community.
