Twitter chats are a great way to participate with like-minded individuals in your community or industry, as well as possibly to get new Twitter followers. It also allows you to find new people to follow as well. Twitter chats are usually about 30 minutes to an hour once a week. During the set time, there is a moderator who starts the chat with a discussion question or topic. Other participating users then chime in on their Twitter accounts, all using the designated Twitter chat hashtag.
