A currency is a tool for mass-collaboration. It allows communities to cooperate better and for their members to specialize. It can also be used to allow teams to collaborate with each other and with those who choose to contribute resources to realize a vision together (such as building a product, creating an experience, or other.) In doing so, everyone can share in the upside.
Similarly, the value of a blog is how much work each post does for you in aggregate. You want a collection of content that all has staying power and continues to drive traffic down the road. Some posts will get only a few views initially but continue to receive a few hits every day for weeks or months thereafter. Others get a lot of traffic initially, then zero next week. Still others get almost no traffic organically but might be highly effective when emailed or shared on social, acting as sales-enablement content or fodder for social follower growth.
