Worth keeping an eye on the work happening on the WordPress dev site about standardising phpdoc markup for actions and filters:
I think they are going to post another update soon about whatever they format standardise on, but this is something BuddyPress should also try to do going forward.
For the record, BP has 2614 actions and filters:
$ grep -iR “do_action” * | wc -l
$ grep -iR “apply_filters” * | wc -l
