I can'r really comment on the quality of my own handwriting (nerve damage in my right arm from motorcycle accident years ago means limited dexterity in that hand) but observing others, like my daughter, her friends, etc. handwriting - yes, handwriting quality seems to be suffering. As is grammer, sentence structure, and punctuation. ;^)

I fear that like many of the skills we as people used on a daily basis, computers, automation and our 'convenience oriented' lifestyles are causing us to lose those skills like handwriting.
