Activity Feed Issues

Guess this doesn't fall under the Notifications bug thread.

I've been trying to catch a clear example of duplicate activity feed updates, especially in the Your Friends category. I think this one illustrates that a dupe occurs when you are following both users in the conversation.

Here the username capitalization is getting swapped, because of course the alert phrasing doesn't change, and my guess through observation of non-dupes is the system generates the message with a capital username based on which profile generated the alert, so I got one for each:

Since there is a now a rate limiter that prevents posting to someone's wall twice (grr), that can't be the reason for this kind of glitch.

Thanks for reporting, will look into it.
