I think I’m on the side with @erlend_sh, I’m not sure a typical participant cares that the category/title were changed.
As a participant, why would I care if this topic was moved from Feature to Bug or to UX? I wouldn’t. Why would I care that the title was made more/less descriptive, or a typo was corrected in the title? I wouldn’t.
The biggest part that I would care about, is the original post. If that significantly got altered, then I care, as it could alter my response and any future responses. But again, not sure I see that as worth showing an indicator.
It would be nice to see if there are metrics for how often a title/category is changed on a relatively active site.
These all make sense. Today, they are distracting, especially banner and pin. Unlist, eh… we use that a lot at Sitepoint and it is occasionally nice that it is very noticeable so the user sees it.
I’ve always felt their presence was a bit too strong in most cases anyway, so I look forward to them being a bit more muted.
