Ian replied to this with pretty much exactly what I had been going to say.  I 
just want to reiterate that the idea of "ping" is to track what the user 
selects.  Each time the user selects something, it's a new event that needs to 
be recorded.  Hence it's non-idempotent.

As a simple example, a site that provides search results could use of pings to 
order those results (the ones users follow more could float toward the top of 
the list).  This is one of the things ping is meant to support, in fact.  And in 
this situation, pings are clearly non-idempotent.
