Hi... take a look at the URL I'm providing to my site (in site details).
If you follow the link to an event category (for example the link that's created on the stream item for a newly created event), then you get a raft of stream entries that out of context make no sense... include "Author created the event", "Author updated the event details" and "Author featured the event"....
These would all make sense if a link / reference was made to the event in question.... but none of them have that.
So not a critical issue - but perhaps something you can consider for user experience improvement.
