Via the Bokardo blog:
The article he wrote on Brain Sparks talks about some of the benefits that include more data and trust.
I think there’s a lot of room for experimentation with social features but you need to have some ideas and research behind it. I’ve seen quite a few just add a feature because they could. I think Beth Jefferson and the BiblioCommons crew have put in quite a bit of research and I’m interested in seeing how it pans out. There’s a lot of things they could have done but when talking with her about the work she’s doing you can tell that everything you see has a purpose and data behind the decision.
I do look forward to more data, presuming it’s usable and shareable.
