This is based on this suggestion by @ForestForTrees. As I'm not sure which cases @Mike specifically disagrees with, I figured it couldn't hurt to make this. Mike made a change so when you submit a post, your activity is updated. However, I think this would be a nice change for conversation and profile post submissions as well. Just wanted to update this with some more information because I think I now see which cases wouldn't make sense per @Mike's comments. The way I look at it, it should update when: A new message is posted (which Mike has already done, just listing it here) A new conversation message is posted A new profile post or comment is posted It shouldn't update when: You like a message You edit a message And I think those were all the cases.
