Pretty much. i keep seeing curl being used as the "back end" of web browsers, fueling the likes of webkit.

Wget on the other hand end up within shell scripts and similar (i have before me a distro where the package manager is made of shell scripts, core utils and wget).

This is a good way to put it, especially since people tend to use them analogously.

+1,

curl is like swiss army knife and wget is fixed blade knife ;-)
