How did people figure out quest back in the day?

[Daldaen]

The developers on Live already said every complete quest was solved many years ago.

The random quests that seemed to have dead ends, like the named animals in South Karana who drop quest pieces (Cracktusk, Gnawfang, etc.) which have no other purpose, are likely a result of an intern's unfinished project. Many cases of this exist in the early stages of EQ.
