From what I hear, regional benefits work pretty differently in the newly released Forgotten Realms Player's Guide. I suggest we just keep to the current scheme, though - have benefits be so minor or circumstantial that they should have no more than marginal impact on an adventure.
Kingdom of Jade: Regional Benefit
+1 on insight checks; individuals from the restrained culture of the Kingdom show very little emotion; a social response to fear that powerful emotions open the way to corruption by the shadow. While this bottling up of emotion doesn't seem to actually be particularly effective in resisting corruption non-members of their culture often find them excruciatingly difficult to read in social situations. They receive +2 on social bluff checks against individuals who are not from their region*.
(*)For the avoidance of doubt we reiterate that this bonus only applies to social situations. Uses of the bluff skill to Gain Combat Advantage or Create a Diversion to Hide (phb 183) do not receive the bonus.
Now I realize the first thing that someone will say is likely that I am looking to get a better deal, I cannot deny that. However there is a disparity in this comparison that is quite obvious. The Valley of Bone has 3 benefits the first applicable to all endurance checks, the others conditional. Where the Jade Kingdom only has a single bonus which is conditional and in PbP settings probably going to be handled by RP more than stat evaluation and "rolling".Valley of Bone: Regional Benefit
+1 endurance checks, reflecting their resilience; The combination of respect and confidence they have in dealing with the unliving can be a potent tool... .they also receive a +2 bonus to monster knowledge checks involving undead and a +2 to diplomacy checks involving undead that they have correctly identified. These bonuses rise to +4 when dealing with undead that originate from the valley of bone (disposed as they are to interactions with mortals, they are more tolerant living who display the proper respect, often giving them an opportunity to speak when more typical undead would simply attack.)
Sorry warderbrad, but I simply don't agree. The Kingdom of Jade benefit is far better in my book, social situations are going to be far more common than undead encounters in most adventures and +2 to bluff for them is amazing! The Valley of bone powers are far more situational, how often do you make diplomacy checks with the undead in an average game?
As for insight and bluff being handled by RP alone with no rolling I can tell you that that is not true of a single L4W game so far. Especially with the events, and common usage of skill challenges which require PCs to meet set DCs in order to score a success. In the three games I am involved in bluff has been used on at least two dozen occasions, and twice was a primary skill in a skill challenge, and there has been one undead battle where nobody bothered to roll monster knowledge.
If I feel one is clearly better - which I do - and you feel the other is then they are likely pretty well balanced.
Of course this may not be true for your character, but I don't really feel that is a problem, regional benefits give an incremental advantage to certain regional stereotypes partly so that the regions populance is more appropriately represented in the player pool.

Uhm. To be honest the Kingdom of Jade benefit seems better to me. +1 to insight at all times, and +2 to bluff most of the times? Also, no, you do roll for social skill checks in Pbp... at least, in my experience, and in living4e too.
