Having not read much face-to-face, I can only tell you that I just ambush my own brain and gut with as many questions that pop up, and keep going back-and-forth in my mind and between my gut until something stands out more strongly. It's tedious, and tiresome, and I'm pretty sure I wouldn't be able to do that in person. I'm a bit socially awkward anyway, when the spotlight is on me (otherwise I can be myself a little more- more open and friendly when the spotlight is not on me) and so, if I asked questions like Manda suggests that she does, I'd probably come off as incompetent and not knowing what I'm doing... because there is that added element of stress, knowing they are watching and waiting to see what I'm going to say or do. Perhaps I need more practice to get more used to myself and how I'd do face-to-face, but for now- getting it "right" comes much more easily if no one is around, and I can battle this out internally with unscrupulous logic, and overflowing emotional intuition. A third element (another person speaking and making suggestions) would just throw me way off. Yes, I'm wound tight, I guess. LOL
So, experienced online tarot reader? Yep.
Experienced face-to-face reader? Nope.
My answer is experience would play a big part, yes. If you asked me for a face-to-face reading right now, I'd probably bomb it horribly.
