Partially correct.  If it's a small example program, or if it's only 
going to be used by developers or other folks who could make use of a 
stack trace, then sure, just throwing the error often works.

Many times however that does not work, and then you have to catch the 
error, log it, and then possibly rethrow with a different exception that 
some higher level code is able to catch.  Or you can skip logging it 
here, if you re-throw and you know the higher level code will log it. 
It takes about 20% art and about 80% prior-planning, but it's not hard 
to work out ways to handle errors and logging in any give subsystem.

For end users, the best way imo is to have main catch all errors, then 
log and attempt to upload it to a central site.  This avoids having to 
ask the users to dig through logs, up load them, or interpret them. 
It's just easier on everybody, yourself included.
