Dave is freakin' because the limitations he sees in the RSS system are not seen by others. Either the limits don't exist and Dave doesn't understand or he does and no one will see them until a crash. He may be in part right but this is never the answer to anything:

...should an aggregator be polling every 30 minutes? The convention early on was no more than once an hour. But newer aggregators either never heard of the convention or chose to ignore it. Some aggregators let the users scan whenever they want. Please don't do that. Once an hour is enough. Otherwise bandwidth bills won't scale.

It is a real problem because if everything gets syndicated to everyone by keyword topic, the internet will crash especially if the semantic web guys get their way and everything links as well. But does he really expect that I will only get my updates every hour on the hour? Good reason to go nutty but don't expect this is the solution as the marketplace will not allow it to be the end.

By the way - the calling this stuff RSS over the long term is like calling the web the HTML ISH. Another word will pop up from a source other than Dave, we will all accept it and that will be it. I vote for FLARB.
