When we look at policy for YouTube, the same considerations we discussed for other platforms are important.
Point-of-Contact: Your company should select one person or a team internally who can handle all of interaction among users of YouTube.
Content: Your company should determine a policy stating which employees have access to the company's YouTube channel and have the rights to upload and share videos.
Comment Response: Your company should create a protocol on who responds to comments and on how negative responses are handled. Some companies will not respond to negative tweets; others see negative tweets as opportunities to engage in a discussion that can change mindsets by posting and responding appropriately.
