Physiologically too, they're very different. The anterior commissure 
mediates principally archi- and paleo- -cortical informations (mostly 
concerning olfactory cues, but also more complexe informations). The 
splenium of the corpus callosum "interhemispherically" join the
neocortical areas from the posterior frontal lobe, the parietal lobe and 
parts of the temporal lobe.

Sound just like: "with the internet, who want to make the effort to 
search by himself, even the simpliest information." :) :( :) :(
