My Something Awful account recently turned 20 years old and I signed in on its birthday for the first time in over a decade. I felt the same thing as you. I looked for some new feature or something to show the passage of time, but found nothing. I had to manually click through pages. Forum signatures still exist.

I also posted in FYAD enough to have my own "personality". Some of the posters from my time are still at it, with accounts pushing thirty years old. I wonder if we ever interacted.
