It's curious -- I was not able to submit a direct link to this article, getting an "Unknown or expired link" error.
This has already been posted at least a couple of times and there's at least one existing thread with numerous comments already. Unless that thread has been killed/flagged to death, just use it?
Normally submitting a dupe would bring up that thread, which didn't happen either.
Maybe it's been killed by the mods then? Not sure. Search might turn up the other thread...
