The poll phrasing suggests bias. You could've easily just said the "original or alternative", but to put "cluttered" and "cleaner" in the options, you are trying to sway the vote towards (what sounds like) your own opinion.

So you had 2 options...

1) Ask the Pinside masses an objective question and see how they actually feel in an "A vs. B" choice.

or

2) Ask in a biased manner that injects your own opinion into the phrasing. It's like asking a bunch of kids "Hey, do you want to be on the cool team, or on the team of losers?" You're trying to persuade votes, thus making your misleading "Alien Art Poll"... well... bogus.

One actually opens up the conversation for dialogue, critique, and constructive criticism. The other immediately devolves the conversation because no objective choices are presented.
