In a recent article, the question of whether Twitter was a useful tool was put to a panel of CIOs in the UK. The comments are interesting and we thank silicon.com for publishing them. On our companion site, CIORANT, we explored why CIOs might not be using Twitter or other social media tools. Bottom line: many organizations have a decison to make about how “open” to social media they want to be and this openness starts at the firewall. Beyond that, there is a bit of science that has yet to be applied to the question about whether productivity, privacy, information security and assorted legal issues exist. Until that gets sorted out, look for zero risk approaches to be the rule.
