I even strip 'www.' if it automatically redirects. Marketing tracking parameters add no value for me or my readers.
On HN I've seen a marketer or two who added tracking parameter in comments. It was something like &utm=hackernews&&utcampaign=betalaunch&utsource=comment. That's a bit much IMHO.
I don't get why they add them when posting on HN. It's a senstive crowd and they can still figure out that the traffic came from HN by logging/tracking the `Referrer` header.
