Lynx is going to send the page to stdout, which cron will collect and 
email to you unless you have redirected to /dev/null also, so I don't 
see a big difference there.  For static pages wget can use -N to only 
get copies after they change, and the -O option to control where it 
goes, which could be /dev/null if you really never want to see it.

Yes, but I'd recommend doing 'man lynx', 'man wget', and 'man curl' so 
you understand the options and features of each.
