Comparing both Skype (text only) and email/forum reads, the experience is similar. I feel I have more time to feel the energies there without the distraction of someone (in person) waiting on me in person.
On the other hand, I have done readings in person, and it is lot of weight because most of the expressions are like.. "ok, what am I in for?" Like they're scared. It's not good to let that energy overwhelm me. It does make the translation from card/energy to English language even more difficult at times. To focus on the reading, I just point out what is shown in the pictures and go into description mode and how that relates to the querent's question.
Not to go on and on, it gets exhausting to talk so much and answer questions, too, especially if they don't understand something or know too much about tarot.
