Yes, I’m not. My kids, who are teenagers, think Tumblr is awesome…. They discovered it about 6 months ago and told me how excited they were about it. I laughed and pointed out I’ve been on Tumblr since before they were born… they promptly blocked me. Which, I think is fine, they deserve their privacy online too.
One kid uses discord as their primary chat platform and the other uses telegram. They use signal to talk to the parents.
