By "specialty website" I mean websites maintained by one or few people that contain a wealth of expert and often opinionated information on a very specific topic. They often look like the CSS was done by a 4 year old.<p>Examples include:<p>https://www.sheldonbrown.com/harris/ - the online bible for bike repairs<p>http://www.reveeveille.net/ - making instruments out of plants (french)<p>https://piano-ology.com/ - everything about learning piano<p>http://www.sticksite.com/ - all about diamond willow sticks
