I am actually quite curious if the original Thaumcraft mod author Azanor is on HN. I know a lot of the original generation of Minecraft modders (pre twitch, mostly YouTube days, Minecraft modding changed a lot post twitch) are fairly senior software engineers (most famous one is probably Sethbling, though he didn't really do modding).
There's a "Direwolf20" on hacker news too but that user has nothing to do with the famous Minecraft modder afaik.
