Twitter is increasingly a part of enterprise HR departments and how they attract and hire qualified job candidates. Huge concerns such as Merck, GE, Verizon, and others advertise openings and other hired-related news via Twitter. One upside: Those Pew findings that indicate the typical Twitter user has a high level of education. Another: Though by no means a be-all, end-all detail, engaging with the labor market via Twitter could increase the likelihood of finding forward-thinking, technology-driven candidates. This could be particularly important for certain job functions such as management, marketing, and sales. Lastly, while Twitter might not completely replace other recruiting channels, it's a low-cost venue: Unlike with paid listings, the only expense is employee time.
