Mike Grehan released an article today he named Who needs SEMPO? - Part deux!, in follow up with his last article. I wrote on the first article and named it SEMPO Scandal - Mike Grehan Gives a Thumbs Down. The thread at Search Engine Watch named Mike Grehan Stirs Up SEMPO Controversy is currently the thread leader in the top rated list. Since then several new threads have been created, to make it easier to follow. In addition, many other forums are covering this topic.
For a list of SEW threads on the SEMPO topic, please visit the Search Industry Growth & Trends forum.
