I participated in a discussion on Phil Ringnalda's weblog the other day. My part revolved around how should a proposed change in the RSS 2.0 be implemented.
1) announce a proposed change
2) requesting comments about the change for a set time period of reasonable length to give those who might offer positive feedback time to discover the proposal and formulate a response
3) When that period ends, the Board then votes the change up or down
4) If the change is approved, a date certain implementation date is announced allowing sufficient time for aggregators and feed producers to implement the change
Even if it were never used, the fact that it existed could serve to be postitive.
