I love these personally curated pages. But lets be honest, the wikipedia page has more information about the conveyer belts listed and it has links to references, e.g. the ADB grant for the belt in India: https://en.wikipedia.org/wiki/Conveyor_belt#Long_belt_conveyors https://en.wikipedia.org/wiki/Conveyor_belt#Long_belt_convey... One area where the personally curated sites continues to thrive is the time-nuts folks. If you have the slightest interest in all things metrology you can lose hours reading about anything from time measurement gear and GPSDOs to policy decisions regarding deccoupling civil time from the earth's rotation.
