the number 7 is a great number.
Absolutely, it follows 6 and precedes 8! What fun!
yea i love 17 as a number the most but both are good
1 and 7 are very similar, it's important to distinguish the upward stroke of the 7 glyph from the long upward stroke in the glyph for 1
yea those two can get confusing
Yep. That might also be why sometimes people use a horizontal line through the middle of a 7 in handwriting.
yea i like that style myself looks clean.
I don't use it much but it's never used in computer fonts
