My wife was actually going to do this for a website. She is a teacher and wanted a small site for her classroom so that the kids and parents could keep up to date with the goings on in the classroom and she wanted to use Google Slides for this since she has used it for work before. I was shocked and was trying to talk her out of it. At the end of the day, she decided the site wasn't necessary or worth the effort so nothing came of it but I couldn't believe she thought to use Google Slides for that.
She wanted to create the site the day before parent orientation. She ended up not doing the site because she figured it wasn't worth the time to make something that the parents wouldn't even visit as the parents of her students are mostly not involved in their children's education.
My main argument against using Google Slides is the URL was not going to be easy to remember when telling parents. I pointed her to things like wordpress or wix that would allow her to have a free account but also would allow her to have a URL that would be easy to communicate. She didn't want to spend any money on a domain name either.
