When speaking on web marketing, or blogs, or rss, or podcasting, or SEO, one of the comments that comes up time and again is "well that might work for a small company, but we are a public company and can’t go discussing financial stuff online as that isn’t fair disclosure."
Having asked several lawyers over the years I get vague responses about "well, that law hasn’t really been tested fully yet". And having suffered through discussions of nexus for web sites and tax law in the past, I can assure you these conversations suck are difficult.
So I find it significant that Google’s chief accountant is clarifying financial results in their blog. I have no idea what he is saying, but there it is. So I will get the question again, and I still don’t have a definite answer, but at least I have some ammo.
