When should I use Write-Error vs. Throw? Terminating vs. non-terminating errors

Question

Looking at a Get-WebFile script over on PoshCode, http://poshcode.org/3226, I noticed this strange-to-me contraption:

$URL_Format_Error = [string]\"...\"
Wri

If your reading of the code is correct then you are correct. Terminating errors should use throw, and if you're dealing with .NET types then it is helpful to also follow .NET exception conventions.
