Hi,
I had thought about that - problem is some people want all their events indexed and if the links aren't followed then all the events won't be found and indexed.
HENCE folks should use google webmaster to say which parameters they want google to follow and/or control the frequency of indexing.
Of course folks can also turn off the navigation and just ensure that enough events are shown in the front view.
I'd be happy to hear any suggestions that take into account all considerations. My best understanding is so far summed up in the 'dilemma' post - basically most of us want indexing but not 'too much' and the webmaster tool seems to be where that has to be controlled
