Produce the team's twitter timeline for the iteration
Source: Thomas Guest
Ask participants to write 3 or more tweets on sticky notes about the iteration they've just completed. Tweets could be on the iteration as a whole, on individual stories, a rant, or shameless self-promotion - as long as they are brief. Hash tags, emoticons, attached pictures, @usernames are all welcome. Allow ten minutes to write the tweets, then arrange them in a timeline and discuss themes, trends etc. Now invite participants to favorite, retweet and write replies to the tweets, again following up with discussion.
