I'm a lurker I suppose. I have recently tried to comment and interact more. And I can say LJ is better for that, it feels more inviting. Though I prefer reading fic on AO3 because of the format of the page, I find it easy to read without distraction, and because if I like a fic I will download it so I can re-read it later. As I have done with the Co-Op many times. That fic is my comfort blanket definitely. And I don't remember ever leaving comments on it for you. I absolutely love that fic, but I guess my general feeling is why would anyone want to read my silly comment, others have already expressed some variant of my thought, etc. I guess I may be a pessimist. :/ And here I am commenting on an old entry! :)
