I would greatly disagree with that. The rest of the world can see complaints on social media, whereas no one knows if the guy in the office is being ignored.
The designated commissar could also use twitter too.
Eh, one person's twitter can be ignored.
These days people get so worked up on social media anytime a brand does anything (i.e. people getting mad a cinnabon for their carrie fisher bun pic - http://cbsnews3.cbsistatic.com/hub/i/r/2016/12/27/a9c2ac0c-3...). I think social media can serve as a watchdog for more important issues, too.
"Our followers on social media and readers can be ignored a lot easier than a guy in our office, so when complaints come in, we can simply sweep them under the rug"
