I think so.
What I read into it is that the "freeping" of polls is almost always a waste of time and a distraction, often pulling us into "Have you stopped beating your wife" sites by --- who else?
Sophisticated trolls.
I'm not sure how this could be. It often takes no more than 10 seconds to click on a poll link, vote, then return to FR.
I look on it as not allowing leftists the sole voice on the internet -- and just possibly discouraging a few or painting a different picture for the MSM, as leftists tend to think the whole world adores Obama. You can sense their shock when even online polls don't turn out as they "should" or when conservatives make pro-McCain/Palin comments (how dare they!). I just don't see how Freeping a poll could possibly do anything but help.
