"Impact" is the new buzzword of the creative class, aka the knowledge worker. Also, it might be noted, someone else cleans the toilets, that comment from the social good person was just argument by example, and a strange example coming from the person whose title kind of most closely resembles advocating for working people. Because the people who actually clean their toilets don't likely talk much about 'impact'. For folks who are worried about groupthink and feedback loops at FB look no further than comments like these.
