When I was graduating from college, I realized that I would soon lose terminal access to their main server. I wanted a place to store my old programming bits and bobs that I could still SSH into. I found the SDF back then and it served that purpose well. At that point, I learned of bboard and I like to read that from time to time (although I have never posted to it).

(For those not in the know, bboard is described at https://sdf.org/?tutorials/bboard-tutorial )

SDF is notable to me because it a shell account plus more things. This elevates it past any computer I can just set up with any Linux distro. The "more things" is what keeps me checking back and what makes SDF special to me.
