I write my diary in cursive to stay in practice; if it makes it unintelligible to anyone younger than me who isn't big on genealogy, that's a bonus.
Day to day, my handwriting is a bastardized fluctuation between cursive and print, and it won't always be the same letters that are one way or the other. Cursive is for writing quickly, print is more legible, upper-case cursive Gs are awful and I avoid them, lower-case Fs are almost always cursive-style because they're nice.
Entries into the legal record I usually print, followed by cursive signature with credentials in SMALL BLOCK CAPITAL.
Having written this out I sound insane, but I think a lot of people write this way.
