...you’ll see that we introduced a tool to filter your searches by popular news sources. This new filter is easy to use and lets you see only stories from specific news sources.
You can also use the Filter by Time tool on the left column to narrow the search results by time and see stories published within the last hour, day, or week. Choose “Past Day” in the news search result page for the query “obama,” you’ll see only results published within the last day. The document count next to the news sources on the left column will update to reflect the number of results published within the last day. Of course, our rich results for news images and news videos are also updated with the past day’s results.
However, Yahoo gets points for allowing users to to narrow by source and for including the total number of results for each additional source from the left margin (at the top) of a results page. Here's an example.
Main News Results New Features
+ Scrollable image results
+ More rich results with enhanced News Topic shortcuts
+ Twitter shortcuts showing the latest relevant tweets about the news topic you’re exploring
Sports
We’ve packed some great features in the brand new left column on Yahoo Sports search results pages to help you explore the latest news, commentaries, scores, photos, and videos that matter most to you.
...Another cool feature in the left column is Related Searches, which features conceptually related topics. For example, when you search for New York Yankees, you can also see information about the team’s main rivals (Boston Red Sox), other professional sports teams in the area (New York Mets and New York Giants) or the team’s fan network (YES network).
...rich sports results on the top of the page. For example, as this year’s NCAA basketball tournament gears up for the final four this weekend, you can keep up with the latest action by searching “ncaa tournament” on Yahoo! Sports. You’ll see NCAA tournament coverage, featuring scores, schedules, brackets, and March Madness news at the top of the search results page.
If you haven't used Yahoo News Search or Yahoo Sports Search in a few months/years, this might be a good time to take a look and run a few searches.

Recently I have found myself cooing over visualisation maps (and heat maps) of health and well being resources. The content rich data is overlayed with mapping technologies, and some interesting themes and patterns are emerging.
A lot of the talk around social media in the last year has been around information overload. Social media has provided us with new and exciting ways to create content. But it has also meant learning new ways to manage and engage with social media tools. Are we teetering on the edge of an information overload precipice?
Information overload is a figment of your imagination. Or a failure of your filter. Or a symptom of your technological submissiveness. Depends on who you ask.
What if you had to sort through 3.5 million articles and social media posts a day and try to pull out the most relevant items for your organisation? What if you then had to cobble it all together into something readable for your top groups and executives in your organisation?
