Is filming childbirth on the family camcorder passé? The wife of Twitter's CEO, Sara Williams, tweeted through labor Tuesday morning. At 4:30 AM, she tweeted, "Epidural, yes please," and in another noted that she was timing her contractions with an iPhone app. Over 14,000 people are following her through the process, which she describes as therapeutic. Another woman who tweeted through childbirth told CNN, "I would literally be coming down from a really painful contraction and I'd be saying, 'Give me my iPhone!' and [my husband] would be saying, 'You are weird. Why are you doing this?'"
