VOEvent "Breaking News"?

[Andrew Drake]

Hi,

I believe the detection of the predicted outburst of the
recurrent nova U Sco was certainly one of the events of
the week:

It is certainly one of the most widely followed events.

The CBAT and IAUC are more like the entire cnn website or google news aggregation.  What I think Rob is getting at is a mechanism to push out the most interesting events where "most interesting" is somehow determined by an editorial board (human or robotic). Those events are the "headlines" not just a random Reuters news article in the Sports section about the latest tantrum of a tennis player (i.e.. Murray) in Australia.
