Though not the cornerstone of social media strategy that they once were, Tweetchats are still an interesting way to meet new people and showcase experience and expertise.
The way a tweetchat works is that the host of the tweetchat chooses a hashtag that is not otherwise in use. By following this unique hashtag people are able to follow a single thread of conversation and engage with one another, without the distraction of the full Twitter stream.
The tweetchat typically follows a question and answer format. The admin or host of the Tweetchat will pose somewhere between 3-10 questions, and open it up to all who follow the hashtag. What transpires after that is a free-flowing multi-directional conversation in which people can talk about all manner of different ideas and opinions relative to the question that has just been asked.
