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].
