Personally, I dislike Reddit. I hate Discord. Social media keep getting more sophisticated and more complicated and more confusing and more frustrating. I participate in some other specialized forums with sophisticated forum software that has some good features but also a lot of confusing features. At work, we change software every couple years, and it keeps getting worse. I miss USENET, except regarding images.

My top request here would be to fill in my email address automatically when I start typing in the email field.

As for the potential for vanishing, I do not know what Ninja does for backups, but it would be nice to have a full cloud backup that several trusted people could access in emergencies, but that would cost money.
