Interesting results- for some reason, I was expecting the majority to read with reversals. Personally, I voted for "No but on rare occasions.." because the way I shuffle just doesn't yield much reversals. Sometimes I may get a sudden feeling to shuffle a different way that does produce reversals- in which case then, I read them reversed. Or if I'm reading for someone, I always let them shuffle whichever way they like...and if that caused reversals, I read it that way. I'm more the whatever comes is however I read it...but since I don't shuffle in a way that mixes the card upside down, I end up reading upright readings most of the time.
But this brings two questions to mind:
1) How do you all shuffle? Do you shuffle like you normally would a deck of playing cards where they normally don't get flipped upside down? Or do you place them down and move your hands all over it and mix them up nicely?
2) And finally...for those who do read both reversals and not, depending on your intuition at the time, do you "tell" your cards how you're going to read them ahead of time? Like "This reading, I would like to read reversals too.." sort of deal? When do you decide if you're going to read it reversed or not? Before or during the reading?
When in doubt I have asked new decks about using them inverted, and the answer has been "go ahead" - which of course really means that my high self sees the need for me to use inversions, not that those pretty pieces of cardboard have actually have a preference. 
The only thing which might hinder me from using inversions is if the card backs were strongly asymmetrical, but if that was bothering me I would just draw with my eyes closed, which I often do anyway.
