Usually people post their readings because they either aren't sure how to interpret some of the cards in context of the question or want a validation of what we hope to see. We all want to be sure we are interpreting the real message correctly, but when it's too close to our hopes and fears, can't. RW Carter said about everything I was thinking already, but ...my thoughts include this:
One of the reasons we read, especially for love & relationships is we don't trust our gut feelings or have real faith in that Other. Clue #1 something isn't right, because if it was, would you have all those questions and doubts or even feel like doing a reading on it? I discovered I only read for myself when I'm feeling insecure.
We grasp for anything that can be construed as "good cards" and spin the positive and often delude ourselves in the process. Almost everyone is guilty of reading cards they way we want to see them, I have learned the hard way, many times over, that sometimes when cards seem to be saying one thing to me, the reality was not even close... and ignored it to my peril. It seems like the ones that seemed so positive and wonderful were more likely to mean something I didn't want to hear at all and so would not hear it.
I don't think anyone can be completely objective, we still bring our own biases along when we read and give our own interpretations. I can see that in responses to questions in Using Tarot Cards and Your Readings... oh, that person has had bad experiences and no faith in love... oh, that one is a dreamer... this one has their blinders firmly in place.
But it's still up to the person who did the reading in the first place to decide what those cards mean for them. Asking for insights & opinions is opening yourself up to a plethora of differing views, but if the majority of responders are seeing similar things, then perhaps the reader might want to pay attention to that.
