@matigo A chicken post is pure inside baseball, whatever that is. :)
Here's my own response to the same post [jeremycherfas.net] that seems to have triggered the podcast.
For what it is worth, I don't believe that any something is going to do the job of replacing FB or Twitter. I'm more interested in how people can avoid the worst of those silos, for example by disengaging from the data-sharing as much as possible, or silencing retweets, which apparently makes the Twitter experience more bearable.
If people want out, they'll find way. I mean, people squealing about how am I going to share things with my family seem to have forgotten things like email.
