Speaking of XCode is there a public mailing list for XCode 4?     That is something similar to [MacRuby-devel] that covers usage, bugs and other issues the new IDE is sure to bring.  Apple might have something open to all users but I've had zero luck finding it

There'a forum, rather than a list. https://devforums.apple.com/community/xcode4

There is also a mailing list: http://lists.apple.com/mailman/listinfo/xcode-users
