Besides cursive not being taught anymore, apparently, people don't have a lot of opportunity to even really sign their name anymore either.
So much stuff that I sign nowadays is all on a screen, and they either want me to use my finger, which is ridiculous to do, so I end up with a halfassed "B" and then pretty much just a straight line, or else a lot of even legal forms let you choose from a selection of your name already "pre-signed" in some form of cursive or other, then you just point and click your way through.
Honestly, at that point a signature is almost worthless, because certainly none of my electronic signatures even remotely resemble my actual pen and paper signature.
