Nick,
forgive me, I have no problem with trackers. and just to be clear these trackers are not threats or abuse in any way.
Almost all sites use them to analyse the demographics of the visitors. They also rather cleverly manage to compare your other places visited where the same tracker is used so that they can build up an overview of the sorts of site you visit and generally direct relevant adverts at you. That's good, it's what pays for a (mostly) free internet.
In this I support your statement about a free resource, and yes we can all learn from Stuarts generous free postings, I applaud his largess and desire to give back to the woodturning community. I have been following his site, development of new tools and useful gadgets for a few months now.
But as for the trackers, Google of course is one of the worst generally, but in this instance they only has two trackers on this page;
Facebook is trying to get more heavily into advertising and has (or allows) a whole 2 trackers on it's site;
One of my favorite sites for funnies has 42 trackers, these take 145kb of data to download onto my and anyone elses computer;
But 650+ is an awful lot and these take up bandwidth hence download speed and time. And most of the trackers are not connected to Stuarts site or Vimeo (the video system provider). I was shocked and just find that a little excessive.
So lastly my apologies, I was not trying to say don't visit the site, and agree I was probably a little overzealous in making the comment I did.
