What is Twitter?
Twitter is a broadcast medium with no barrier to entry - anyone who is tuning into Twitter can pick up anyone else’s signal.
The power of twitter for group discussions is that it enables a parallel threaded discussion where many people can talk at once and the discussion is captured in one place, as opposed to a webinar or telephone conference which (only allows a serial threaded conversation and) limits the conversation to one person talking at a time and requires others to be muted.
You can read what people are tweeting, identify and reach out to others who have similar interests, and engage many people in an actual conversation in real time, as well as respond to a conversation after it has occurred. No other platform enables you to search by topic and directly engage with the originator of the content without jumping over obstacles, having to register within the platform, downloading software, or providing personal information to participate.
