Use the new API for your Leaderboards!
The leaderboard programming crew’s priority should be making the current leaderboard information available via the API.
If sites like MoS (and many others in the coming weeks) are competing on finding the best way to display these things, the best additional features, and feeding feature requests back to ArenaNet, we will end up with much better resources for the community. Why would we want ArenaNet to spend its time competing against its community in providing services that the community now has the (excellent) tools to provide?
Simple, really. Because an official and appropriately detailed leaderboard is something that should be supported by a company that encourages competition in its formats. Besides, I don’t think the team developing the API are the same guys that develop the leaderboards, so working on one using the developments of the other shouldn’t impede any of the API enhancements that they plan on doing.
