so far, google+ has better UI, but i'm not convinced they actually have better policies in the long run. structurally, in terms of how data / photos / media are shared, this is not significantly different from Facebook.

real innovation would come when they start considering relationships not in terms of what is shared or not shared, but how that accumulates to different forms of knowledge over time, by augmenting or amplifying awareness, by enabling people to stay in touch better, by preserving visibility across people & circles despite differences in posting/update volume, by enabling back-referencing and re-living. i can't repost / share this comment with the rest of my circles; so i'm not having better / more fluid, circle-crossing conversations here, either. this isn't innovation - yet. it's usability.
