It's hard to know what to say to introduce myself or something. Most of the people who are still around reading this are people who've known me a long time. If there's something you'd like to know, feel free to ask.
Having people know me for a long time is both good and bad. For most people I'm not (just) who I am now, I'm the arc of who I've been over the time they've known me. I try to improve myself, to examine my life, to evolve, to adapt to change. But that doesn't mean people change with me, or that the change in me erases what they've known and interacted with in the past. It's not possible to escape your past, even if you want to - which, mostly, I don't.
The plus side of this is that I've got friends now who've been friendly with me for a significant chunk of my life. Thinking back on it, that hasn't happened since childhood. I rather like that. My friends, let me introduce you to them.
