I didn't see any updates about this, but I assume that, when posts are edited, new pings are created? I got four pings for one post earlier. It's great that you can now edit people in if you forget and they still get pinged about it, but it's sort of annoying getting multiple pings for a single post.

Anybody else getting that?

Its happening to me as well. I got 4 pings for one post yesterday.
