A few months ago I was writing on G+ about how we are not using the Hypergrid to its' full potential. This, Vanish's hypergrid tour and the cross-grid sci-fi roleplay are some of the things I think are great and wonderful developments.
It's been awesome to watch the hypergrid community take this step forward, I hope we continue to do so and to explore new avenues for cross-grid collaboration -particularly collaborations that showcase small, free and independant grids.
