There are many great tutorials in tutorial section, but navigating them can be quite difficult.
A quick search showed me that some suggestions were proposed before, but I haven't seen any change.
So I'll propose them again, with some new ones:
Also tutorial moderator (PurgeandFire ?) could give a better insight into need of any change.
And if something is planned for Hive 2.0 I would like to hear about it.
