Drew..great strawman but it assumes at least two worse case scenarios.
Um, it wasn't a strawman's argument, but whatever.
1) All polls will come down to a black white choice all the time.
A poll restricts you to the choices given. Even if there's an "Other" or "None of the Above" it's almost always devalued compared to the choices expressly given. That's just the way it works.
2) People will be forbidden from chiming in other than selecting a or b.
No, but if they are expressing unpopular opinions their arguments are devalued by the poll results in bold at the top. This is not a problem if "popularity" is what is being measured, but if popularity is what is being measured it really doesn't matter if one chimes in or not.
They have their weaknesses but it is probably among those quickest ways to get general overview even if that overview is skewed
Some people come to forum to read but lack confidence among more experienced people to chime in. Some people fear over the top responses from overzealous fanatics on some topics. Some simply are short on time and would gladly check a simple poll. There are infinite possibilities besides laziness.
On the one hand you are admitting that the number is skewed, but then you appear to be arguing that it is important to count people who might not be willing to post, for whatever reason, but would answer the poll question.
If you don't go through the proper steps to make sure you are obtaining a representative sample and don't run the appropriate statistics, how do you know what the margin of error is on whatever number you get out of it?
If you are convincing yourself that the numbers somehow mean more than they do, then that is the pseudoscience point I made earlier. It is very easy to fall into this trap, but you either have to do the work to establish the level of confidence in the numbers or else just disregard them.
And if you can't have any real confidence in the quantified results because you don't know the margin of error and whatnot, then what's the point of doing a poll where the only added value is getting quantified results?
