According to Mashable, Google+ just launched Trending Topics Thursday night, November 18. It’s similar to Twitter’s Trending Topics and includes 10 of the hottest and most popular discussion items on the social network. When a user clicks on one of the topics, a search query is launched and posts about the topic by other users on Google+ are displayed.

In addition to adding Trending Topics, Google also made some changes regarding Google+ Search. Users can search the entire Google+ network, within their circles or within their own posts.

Trending topics helped Twitter become the place where people turned to find out what others were talking about at any point in time. Now with Google+ jumping on the Bandwagon, does Twitter have to watch its back?
