I'm really excited about the External Grants Working Group proposal. The group of people have already show great skills in coordinating grants and I'm confidant that they will bring great results. I also love how we use the existing grant money to fund even more awesomeness in the future.
The mutable messages grant proposal looks very well put together. @ev has been very response to the feedback giving and that he already has a working propotype is a very good start. It's also an important piece of the puzzle so I'm fully behind this.
My first reaction to the implement SSB in C was a bit of caution. Another implementation and C hmm. But then I started reading the proposal and especially this reply and I got very excited about the possibilities this brings. I think this really shows a lot of the flexibility that SSB has.
