I am constantly surfing about in my quest for knowledge and information about how and why things work or not as the case may be.
Has anybody ever throught about why a bridge is where it is?
What the threshold for forgetting that something was ever done?
Here's a factoid that goes to a historical perspective on something everyone just knows:
"In printing, a cliché was a plate cast from movable type, also known as stereotype. When letters were set one at a time, it made sense to cast a phrase used repeatedly as a single slug of metal."
Neat huh?
The printing thing is well known if you have studied design and typography. Similar to upper and lower case. In that there were fewer 'upper case' letters then lower case. Because lower case has letters with cedillas, umlauts, theists and numerals. So the lower case sat in the larger, bottom of the case, hence lower and upper case. Fonts came in cases, that were looked like suitcases – hence the term 'suitcases' in typography. There are also reasons for terms like leading, kerning etc.
