How dare DS folk individually vote how they want to in answer to the specific question, and not how I want them to vote, the deluded souls.
It's a disgrace, I tell you, a disgrace.
Oh, and OP, before you sound off about different polls, try maybe comparing like with like. There is an important difference between "Week 11 : Who was your favourite couple ?" and "Who is your favourite ?"
You also say "even in a small sample" as if that's something positive. All things being equal, a smaller sample is less reliable.
The truth though, more importantly, is thal all polls, where not from a totally random population, are very much effected by to whom they are asked. I doubt DS or Hello readers are particulatly representative, but the polls do give some vague indication and are quite fun to see.
