I may be weird, but I almost never use the threading macros, and routinely use comp and partial, often with map. I often order function parameters in my definitions to facilitate the use of partial. I don't mind reading functions "backwards" in a long chain of function calls, even though I sometimes use threading macros. I think this is just a matter of taste and past experience. I agree that it can be clearer sometimes to arrange function calls "forward" in the order in which they're called. Obviously, a (small) disadvantage of e.g. -> and ->> macros is that they depend on having a series of function calls in which it's the same argument (1st, or last) that has to be passed on (although you can wrap the calls in e.g. #() to fudge that). I think that for a new user it's probably a little bit confusing with -> to have a series of function calls in which there's a hidden argument right after the function name. With normal function composition, all arguments are explicit, and you can pass the result of any function call as any argument. I don't think anyone would disagree with these points.
