I attended a font master class given by a graphic designer at the unveiling of a new font he created. Fascinating stuff.
Most of you have probably seen the meme illustrating the extreme meanings the same words in different fonts communicate.
I learned to avoid the use of script fonts in nearly all cases (despite the personal, elegant impressions such fonts achieve) for the uninteresting reason that they can be difficult to read.
Consider how much more the case this is given that fewer than half the 50 United States currently teach cursive in schools, and several in that number only recently reintroduced the curriculum after a long omission.
Sometimes, though, the script style font just...works. Take this 5-inch oval plate of mine, a longtime favorite.

How much less funny would my kitchen staple be in Times New Roman or Helvetica? Or birdless?
