Is there much happening about this (symposium aside)? I read Tim Berners Lee's book recently and was intrigued by this idea.

I set up a pod (I think) and a Web ID (I think) but overall found the whole thing quite underdeveloped for an end user. To be fair, they do say it remains in development and is really aimed at developers. So that's fair.

I really like the idea though.

Peoples’ thoughts on it?

I read about this years ago. It seems to not have gained momentum?

I think it's still very early in development. From what I have seen/tried, it's not fit for regular Joe consumption yet, and in fairness they are clear about that themselves. I love the concept though, I hope it becomes more mainstream.
