I began my writing journey on fanfiction.net after a fan page on wetpaint.com went down (wetpaint was my OG springboard for all things fanfics, then ff.net, livejournal and tumblr). I still visit it from time to time, reading fanfics that are not present on AO3.
What about you? Do you still visit ff?
An understandable choice. Last I checked, FF was a ghost town.
