If you can’t think of anything to search for, there’s a list of hot topics on the left. But I did a search for soccer.
The results are divided into three parts — at least I think that’s how it’s supposed to be, though it didn’t turn out that way for me. The first part is the summary, which shows you a live update of links from Twitter and Facebook (or Twitter and Twitter — more about that in a minute) and shared links. The second part is supposed to be just updates from the social Web but Bing kept telling me there were no results. Um, no results for a search for soccer? I dunno. (Update: Later I tried it and it worked fine.) The third part is the list of links that are being shared. You can see who has shared the link recently, or get a full list of places the link has been shared.
Though both Twitter and Facebook are included in Bing Social Search, Twitter tends to drown out Facebook due to sheer volume. I saw some Facebook updates in my search results, but not many. Bing does give you the option to specify the social network on the left, so you can turn the Twitter updates off.
At the moment the firehose of output is so lopsided between Twitter and Facebook I’m not sure I’d use this — I’d be afraid I was missing some interesting Facebook updates in the Twitterlanche. However if/when Bing Social adds more sources to its search, and I can search between them while leaving Twitter turned off, it’ll be useful.
