Google is rolling out a new hashtag experience in Google Search today that will see search results for queries with hashtags display related Google+ posts and content from other social networks:
– When you search on Google for a hashtag, say [#AmericasCup] or [#WaterfallWednesday], a set of relevant Google+ posts may appear to the right of regular results.
– You’ll only be able to see posts that have been shared publicly or shared with you.
– If you click on any of these posts you’ll go to Google+, where you’ll see the full set of relevant posts.
– You’ll also see links to search for these hashtags on other social sites.
The new feature will only be available to English users in the US and Canada initially and will go live on Google.com and Google.ca sometime today.
