The polls can be made more informative by analysing the results after a specific time period. it is also not logical to extend the viability of the poll beyond a certain date. The poll on who will win IPL is still open, i think. Also, weightage to polls should be given based on the issues on which they focus upon and an additional option like whether it is assessing the popularity of a product, social or health issues, needs to be added to the poll, so that the context of the poll is clear. Also, there will always be a bias against rating commercial products based on polls as it depends mainly on what each person sees as important in that product.
Instead of a general poll question like "which laptop is the fastest to use", the question can be "what is the central hardware component that determines laptop processing speed". This would make the question that much more informative, especially for students using the site, who can learn something instead of clicking on options based on companies like LG, Acer, Samsung etc., by which they are only endorsing their preference for the particular product.
