These conversations happen in the pub, in the bleachers of our kids soccer games, and just about everwhere. We’re all having public conversations all the time, where the only privacy is that of proximity – you really don’t know who that is sitting at the next table, and usually you really don’t care. Now many of those conversations have moved to Twitter, or Facebook, or your blog. Some of those are open conversations that are easily found, searched, and aggregated and some aren’t.
