I came to divination after long exposure to the Thoth deck in connection with my qabalistic studies, so I have no real fascination with it as a tool for reading the future - at least not for myself. But it's what most curious acquaintances expect upon learning that I have the cards, so I'm happy to oblige with a non-prescriptive, open-ended kind of reading that looks at possibilities, latent tendencies and potential trends in the fabric of their personal reality. I find it's effective for getting them to examine the development of their situation with an eye to taking ownership of it. In that regard, I don't do "just for fun" readings (the Thoth is by no means light-hearted enough for that), even if "entertainment only" is the legal shelter public readers must fall back on. But, of course, I don't have a "practice" like many of you do, so I can pick my shots.
I also feel that there are better tools for this purpose. While still by no means infallible, predictive astrology has more substance to it, and a much longer recorded history of empirical observation. I Ching has a greater store of practical wisdom behind it. Lenormand - with its narrower range of symbolic expression - may even be better suited. "Intuition" is all well and good, but the challenge is to keep it free of the reader's personal bias; if the querent isn't present in the flesh but sits passively at the other end of an internet connection, I can see the act of predictive reading becoming, at best, a purely psychic or "mind-reading" exercise or, at worst, simply a tap on the reader's own subconscious.
