Ah, ok, sorry i think i misunderstood your note because i fixated too much on the term &quot;analytics&quot;.<p>For what i will call &quot;broadcast&quot; events - such as your very valid tsunami, earthquake examples - sure it would be essential for those alerts to get out...But whether you&#x27;re using a centralized or a decentralized approach shouldn&#x27;t matter - assuming of course that one of the nodes of the decentralized method gets the needed input about the alert - in order to pass it on to the other peers of the decent. network.  Much like email and websites, and to <i>some degree</i> mobile phone carriers, having a decentralized network does not necessarily prevent fast distribution of important&#x2F;up-to-the-minute&#x2F;broadcast information such as alerts.  In fact, one might argue that having a decentralized approach might help with overall resilience.  That being said, as much as i am a proponent of decentralized (and open) social networks, they have many non-trivial obstacles to contend with...but i do hope for one day to <i>not</i> have to exclusively depend on closed and centralized platforms like twitter et al.
