Just getting started on twitter? Looking into twitter’s features to see if it is for you? If so, you are probably asking yourself “What are hashtags in Twitter and how do I use them?”
Hashtags are used in Twitter to put a label on a topic of conversation that you want other to be able to find using the find feature. This allows for easy promotion and easy access to that information.
No formal registry is required. Just pick a hashtag (hopefully not already in use) and include it in your post. Announce to others what that tag means and you’re done!
