I am enamored with the idea of SDF, and I think it is an important part of computing history and the present. That being said, I am curious as to whether anyone actually finds it useful—aside from the fact that it hosts the instance!!
For me, SDF is a refuge. It’s a part of the Old Internet where I can go and just enjoy a shell account for its own sake. Usenet, email, and a simple web page. Now with mastodon and lemmy, I feel like I’m contributing to a better Internet of the future while preserving and honoring the technology that started it all.
