Very long post, but I like the explanation of why the English hat makers where called 'Mad Hatters'. I didn't know that! You bring some good information to the community, I just would suggest to reduce the amount of information per post, create multiple posts. BTW, the reason I discovered this post is because of your info on Mad Hatters. I do own a hat that resembles Mad Hatter from Alice in Wonderland; Although not so much about technology, you may like to see it (here). If you place an comment, I'll upvote it to support you.
