• Associate your posts with topics in your company
• Search for updates with common topics
• Find relevant topics fast

Chatter Topics lets you associate your updates with other posts and comments on the same topic by using a hashtag (#). By using hashtags, you create a topic link that categorizes your update so other users in your company can find it more easily. You can also use Chatter Search to find updates and comments that match the Chatter topic you’re looking for.
