You reach one of those “significant” birthday numbers and you take stock, look back, remember, relive. I’m not the person I was. Thankfully my politics haven’t “mellowed” as my family said they would. But my interests have changed. I look at what I was passionate about and remember a very different man. I smile as I see what drove me, what animated me. Did I really get so angry about that very niche thing? I leaf through the traces of countless arguments and discussions, remember deep friendships and bitter feuds. Communities I was a player in. Apps I left behind.
