Along with the new case study, they also share a video from the owners of Boesen and their sense of how Social Media has impacted their marketing efforts:
The case study is not only visually pleasing, but there are real-life numbers. Numbers that any small business owner or social media "guru" can use as examples or models.
One key with this project was how the client (Boesen) was able to articulate a goal, a purpose with the agency (CreateWOW). The case study is yours to download for free (might be opt-in logon by now). Use and share as desired.
Disclosure: I've been doing some work of late with CreateWOW. This is a company that gets Social Media is a toolset that helps us build, not a foundation around which we build business.
