The potential downside can be equally huge. There is little traffic. No likes. No comments. That data - or the lack of them - are made public on the Pulse site. Your client looks bad.
The good news is that Pulse platform allows you to delete. And that's what I recommend. Products fail and are taken off the market. So should op-eds which don't resonate.
To delete, click on "update" or "edit." That brings up the "delete" button. Click it and put the op-ed out of its misery.
