I'm really not clear on what the point of your article is.   Is the that Grassroots is potentially bad because the Kochs are connected somehow? Or is it that you should apply more scrutiny to the groups you report on? If the latter, what kind of scrutiny did you apply to PRwatch, which seems to me as left-wing hate group. Who funds them? They're not too forthcoming on their own website (at least that I was able to find).  BTW looking fwd to see how the new commenting system works out.
