This question already has an answer here:
Over on stack-overflow, I have 2 or 3 questions that have over 1000 page views and its hard for me to believe that they only have 1 up-vote each. I am not saying my questions deserve it, but I have seen some really stupid questions that have way more, with less views. No examples at the moment, but I am sure you have all seen them... This is either due to my questions not being useful at all except for myself, or there are a lot of lurkers out there that find them in search but never take the time to sign and up-vote if they were helpful.
SO should implement a sign in after X amount of web site visits or something similar. That feature is really annoying but if cache isn't cleared then the login will persist... I don't think questions are getting represented accurately enough both positively and negatively. Who knows, maybe all my questions suck and I would be getting 100 down votes.
