Organized chats, such as talks with celebrities, are more likely to take the indirect approach when it comes to participation. If a lot of people are taking part in the chat, or if the host or celebrity conducting the chat can only take a certain number of questions, it's often easier to have a moderator filter through the questions to come up with those that are most relevant. That said, the chat you tried to participate in might very well have required you to download a software component, particularly if it was taking place on a Web site. There are often instructions or guidelines posted for organized chats that let participants know what's expected of them and how they can take part in the discussion.
