I think it does matter. Not just in the direct sense of whether or not I can read it, but in reminding ds that homeschooling is not a cheap lazy way to do school, where you can turn in any kind of crap because it's Mom.
If anything, my standards are higher than those in his school classes. I know what his best work looks like, and I want to see it-- and that includes handwriting (and ds is a lefty, so I really don't expect beautiful Victorian script, but still...)
