Hey guys, I checked with some teams and it appears that this shift was intentional, to make the Wiki Activity feed less cluttered and easier to read (you can tell if things are comments because they say "commented by" on the second line, and there's a different kind of icon associated with it.) However, I'm not sure why this change isn't effect on Community Central yet..
