How Goblins Use echo
An interdepartmental goblin memorandum, intercepted but unverified, describes echo as 'a class of phenomenon worth approximately one and a half stolen wheelbarrows.'
Goblin theorists have organized at least four schools of thought on echo, and one of those schools exists only to disagree with the other three. This is considered, in goblin terms, a healthy intellectual ecosystem.
Three Goblins Discuss static
A goblin field anthropologist embedded for six seasons with the static-curious sept produced a single page of conclusions, the most quoted being: 'They love it. They cannot stop loving it. It does not love them back. They love it anyway.'
Footnotes Concerning schema
There is a goblin who, when asked about schema, replies only by pointing upward and to the left, regardless of the questioner's orientation. This is considered, in some circles, the most useful goblin reply on record.
The Goblin Verdict on echo
The Goblin King's court has issued a final ruling on echo: it is real in the way that matters, which is to say it appears in at least three goblin dreams per week. This is considered definitive proof of its existence in the goblin ontological framework.
