generally important things are :
I like this construction of a roadmap
http://maidsafe.net/roadmap then you can see what happend in the past and what should be happen in the future.
Its Open Source everybody can join and maintaining the code if something went wrong is a good thing to know.
it should be done in a transparent way :-), maybe through proof of dev for amir for example, so people can not say "only another spam coin"
then Goldcoin got a history, we can show whats happend in the past: like the date of start and the protection of the 51 % attack.
Show the Team, with amir as lead dev with a picture maybe, and micro guy of course :-)
excuse my english language im a german i dont like grammar :-)
