I really dislike creating resources to represent transient actions. Not a big deal in the case of a bank transaction as that is something you could easily imagine needing to be stored for later retrieval. A different example is relating one social network friend to another or searching for specific people on the site. Those are things that, to me, are much more borderline and I would err on the side of not representing them as resources.
