I was only bothered by all the claims:
Podping on Hive represents the first way to send a short message to the entire world without relying on any single piece of infrastructure run by a single entity;
HIVE is a dpos chain and at the moment there is a single private key to write entries. The podping-hivewrite is a single piece of infrastructure, which is run by a single entity.
I think when podcastingindex will eventually fail in the future (HIVE chain halts, private key lost, priv key stolen and database flooded with spam) it can easily be replaced by something different.
