‘Employees can use Twitter as a way to move from weak ties to strong ties with experts. Although public social platforms are effective at establishing weak ties (in other words, people you are familiar with but do not know well), strong ties are needed to transfer complex product knowledge.6 Engagement on the platform (such as replies, retweets and mentions) often leads to face-to-face meetings. In those cases, Twitter acts as a natural icebreaker.’
A number of Twitter users were so positive about its potential value that they took it upon themselves to train their colleagues through webinars and one-on-one or small-group sessions on how to use the platform effectively. The training sessions were not solely about the technical aspects of Twitter, which were easy to grasp, but also about ways to increase effective absorptive capacity by identifying relevant external expertise and making it meaningful to company stakeholders so it can be implemented.
There is a lot of good stuff there about really using Twitter at work.
