I've actually changed a lot, I think. DTF was one of the first forums I ever joined. Scenes from a Memory had just come out, and some people were still arguing about Falling Into Infinity, so this was late 90's, at least 15 years ago.
I seemed to me that communicating via words only, with inflection provided by italics, bold, and underlining, was inherently limited and dangerous, and I know myself to be pretty opinionated and basically an asshole, so I didn't post much at first. It seemed better to post rarely, but have something important to say when you do say something, than to just post all the time.
Now I don't give a fuck.
But I think I've gotten better at posting, and gotten to be less of an asshole. And believe me, if you think I post a lot, you should see how much I delete, or how often I just close the window and not post after writing five or six paragraphs or more.
