About four weeks' ago I wrote about Scaling Echo: P2P and Cached Feeds. I drew a few conclusions:

1. The syndicated blogosphere will reach 300 million feeds in 3 years
2. Feed payloads will grow 100 to 10,000 times
3. Each reader may consume 1000 feeds
4. Syndication Growth = Denial Of Service
5. Two architectures will support this scale:
   • Peer-To-Peer (P2P)
   • Caching by intermediaries (communal aggregators)

Jevon wrote about scaling new post pinging.

We need to have aggregators that send their subscriptions into a cloud and get pings back that have gone in to that cloud at any other point. It could be called a "peer to peer subscription and message delivery system", or "distributed redundant notification network", or whatever. But as soon as we can build a message network layer, Microcontent will really be ready for the next level: integration into our active lives.

Phrases like "community ping relay servers", "supernode", and "ping cloud" make my day.
