Personally, I feel that everyone has the opportunity to vote in polls whether their experience covers a few of the options or all of them. I would not limit someones' involvement in any poll I set up - they will always have something to share (whether I concur with their opinion or not.)
Some Whisky is not always available worldwide, and I would rather vote and comment on the ones I know than ignore a poll someone may have put a lot of effort into.
Of course if I have no experience with the subject, I just lurk on the sidelines without polling and see what information will be shared.
PS: And I always delight in whatever gems Mr Tattieheid comes up with!
