What is Content Curation? Tosh.0 as the Ultimate Example | Social Media Content Curation | Scoop.it
If you really want to break it down for your non-marketing friends, I suggest comparing your work to that of Tosh.0 - the internet clip based show on Comedy Central.

This features the best (or worst, depending on who you ask) video clips from the internet curated by the host, Daniel Tosh. True to the definition above, Tosh provides "insight" and "commentary" into the clips, adding additional value for the viewer.
