I believe Notch meant that farlander was already used a lot for other things, not to describe the Endermen. I guess i could be wrong. Here are the two tweets, "/v/ is petitioning me to change the name from "Enderman" to "Farlanders". How about we just rename the "far lands" to "the end" instead? ;D" and "Besides, "farlander" is a more common existing term than "enderman" according to a quick googling."
Agreed.
is it just me, or does that screenshot look kinda fake?
