This is really good to know that now Twitter feeds are being shown in Bing Searches..look at this link http://searchengineland.com/twitter-trends-now-showing-in-bing-results-115258
Yes, this is absolutely true. Bing has started to deliver Twitter trending topics in its search results in recent months, according to recent reports. Bing searches for topics that are trending on Twitter will sometimes bring up results that include a “TRENDING†box showing how many times a particular topic has been tweeted within a certain span of time. When Bing deploys this feature fully, it could be a significant point in their favor. At present Google doesn’t have anything like this, and it’s definitely a useful and interesting feature.
Truly said..Social media will pay a very important role in the search results and no wonders in coming days...we can see the ranking of any webpage decided by how effective you are on these social media....
