Facebook Inc. said Wednesday that people will be able to click a hashtag to see a feed of discussions other users are having about a particular topic. For example, typing a number sign in front of "ladygaga" or "sunset" will turn the words into a link that users can click on to find posts about Lady Gaga or sunsets.
Facebook says hashtags are a first step toward making it easier for users to find out what others are discussing. The company is not giving details about other tools it might introduce.
