Social media provide ample space for staff to amplify alternative views, or muddy a clear commercial message with inappropriate personal content.

社交媒体给职员提供了充足的空间去阐述不同的看法，或者用不合适的个人内容给一条清晰的商业信息添乱。

Before I leave this topic, let me put in a brief commercial message for speaking. I'm not opposed to speaking, I think when students speak, it's fine, but what counts in speaking is not what you say.

在我结束这个话题之前 请允许我讲一段简短的商业信息 我不反对演讲 我认为当学生演讲时 这很好 但重要的不是你说了什么。
