While I'm not a huge fan of what we are calling "Social Currency", I can see why it would be beneficial for companies to recruit and hire employees that have a positive and beneficial presence (or brand) on social media. Rather than looking at past achievements on a static resume, being able to determine in real-time how a potential candidate would work to solve problems would be a great way for a company to find the best candidates for their positions. As a career counselor, it is important to understand how recruitment is changing in this new digital environment and be able to counsel students to have intention with their social media presence and know how to use it to be noticed.
The downside to social currency is that it can also cause false "judgements" on individuals if they don't have enough followers, or enough subscriptions, etc. Some of this kind of rating system is based on subjective assumptions that can be extremely damaging.
