I'm not sure if it's possible with StackExchange's current UI/model, but do you think it would be helpful for both new users and or existing users to have a list of common websites such as the Salesforce API Doc, Visualforce Page Docs, APEX Docs, Server Status (Trust Site), etc off on the side bar to the right?
That being said, if possible, do you think having a section of undocumented features would be nice to sticky as well? One thing I could think of are URL Parameters Salesforce currently supports but there's no documentation on their sites such as saveURL, retURL, clone, etc.

stating that it could go away at anytime, but it does help one possibly develop buttons while avoiding the use of creating a VF/APEX if possible. – Double A Jul 22 '14 at 13:43
