Thanks Laura for this impressive number of expressions.
I often use “la chose” to mean “the subject we’re discussing right now”, as in: “c’est ça qui fait l’intérêt de la chose” or “je suis au courant de la chose”. I find this word very convenient to avoid restating the context.
However, I think that “être porté sur la chose” has essentially a sexual connotation.
