I was gonna write yes, but a few members made a good point about having previous posts "taint" one's opinions. That being said, if some of us read every post, we might also not be inclined to voice our opinions, and then there would be far fewer posts, fewer active members, etc. In all honesty, sometimes yes, sometimes no.

Plus, I don't mind giving someone the opportunity to make a pun out of or a humorous comment about my post. ;)
