I read Jeff Pulver's post this morning. Last night I read the same email from GIPS PR agency. I thought about doing the same thing, but it's my birthday and I figured other would have the same idea and let it sit.
Here's the situation. There's nothing wrong in requesting an embargo. What was wrong was giving the details of the embargoed information in the request and not realizing that without agreement there's no embargo.
Point to Jeff and everyone else whose pointed this out.
