I don't know about others but I feel the wiki is really difficult to navigate as well as being a bit devoid of information. It feels like the information on there is cut to the bare fat but that the useful stuff is also removed. As an example, I saw this on the site: http://www.glorantha.com/docs/how-argan-argar-courted-esrola/
My process was:
"Oh what's Akez Loraddak?"
Center of the Shadowlands.
"Where?"
The God Learner name for the Kingdom of Night
"What?"
A historical empire in Kethaela
"Where?"
A coastal southern land in Maniria.
"Where?!"
A region of central-south Genertela
"Ah, okay."
I can't fathom trying to get into Glorantha as a newcomer and finding this as the wiki. I understand that a lot of effort is in this but compare it to, say, the Lexicanum for the 40k fandom: http://wh40k.lexicanum.com/wiki/Cadia
Almost all the questions you could possibly have are answered in the summary paragraph:
Cadia was a terrestrial Fortress World on the edge of the nebula known as the Eye of Terror. The planet was situated in an area of space known as the Cadian Gate, the only stable, permanent route into and out of the Eye of Terror large enough to allow the passage of battlefleets.[5] For this reason, Cadia was heavily fortified against the assaults of Chaos and was a frequent target of Abaddon the Despoiler's Black Crusades.
And a bunch more are answered by the "Basic Data" sheet which has a summary of all relevant logistical data.
I understand that this would be a lot of effort but maybe a fan-contributed wiki on the Glorantha site might be a solid idea? I'd happily help setting up templates etc, it's just a matter of having the space for it (and also this dodges a lot of possible legal issues, as I understand it).
