I planned to link to the original discussion here on HN, but that thread has been marked dead for some reason. In any case, I think the sudden banning of a site by Google and then re-listing within hours without comment is noteworthy.

This article seems reasonably unbiased, noting the questionable quality of Studio Briefing content, but also noting their length of time in operation.

Edit: Here is the link to the original conversation. http://news.ycombinator.com/item?id=972583
