(didn't see a way to start the thread on the suggestions page)
Waving the wand that says "AP is even more of a worldwide success with 10,000 active users", I am thinking...
It is entirely reasonable for _every_ local club to make sure that every event is in the calender. (with a proper A/B/C/O rating) Given that number of events, it almost demands a filter.
But if the filter were something like:
Show events that are:
A level: AAA m/km distant
B level: BBB m/km distant
C level: CCC m/km distant
O level: DDD m/km distant
Popular: EE members attending
Then I could set a threshold of 200 miles for local meets, 400 for regional and other, and 2000 for A meets, and always view meets that have 50 or more interested people. (and retain the option to "view all events")
Lots of options here - and yes, good thoughts travel...-)
(aside - I'm confident AP will continue to grow - I wrote about it for the ROC membership in a newsletter last year (page 6):
