I think it's fine that Google spearheads this effort, but there's too much Googleness on all of it. Basing parts of it on their existing APIs doesn't seem like wise re-use, it just seems lazy, and a truly half-assed commitment to creating something really open. Google should have taken the path of being a totally neutral steward. Instead they erred on the side of making this an open version of The Orkurt Platform.
