Bruce,

In case you haven't found it yet, they are (basically) the same.

$poe_kernel is exported by POE::Kernel.  It's a reference to the Kernel 
singleton. 

Calling $poe_kernel->post, calls the post method on the $poe_kernel 
object.  While POE::Kernel->post, is using a hard coded class name. 

The only place I'd expect a difference, is if you start working with a 
subclass of POE::Kernel that overrides the post method.  Then all your 
POE::Kernel calls will create chaos.  (Or maybe if a future version of 
post breaks without an object reference, like ID).

The examples for post use $_[KERNEL] to access the kernel object.

Out of distrust for exported globals, I'd do as in the docs, and use 
$_[KERNEL].
