We had couple of discussions during the recent WMCON to standardize Mediawiki User pages to reflect User contributions as a minimal timeline. Even though there were mixed reactions on it, let me quote down few benefits of the same:

1. Would make life of stewards/administrators easy to review/judge user credibility by just visting their user page.
2. Would incentivise users to come back and contribute more (as building their social profile too while editing Wikipedia)
3. Make Mediawiki more futuristic contemporary. Of course, live timelines have been around for ages.

@Florian had this idea of making 'Thanks' public so that an entry in a user timeline would look like:

2017-06-01 09:34: [[Edited| edited]] article [[ link | Articlename ]] and received 5 public Thanks.
2017-06-01 09:00: [[Reverted| reverted]] edit [[ EditUrl | Edit ]] on article [[ link | Article2 ]] and received 0 public Thanks.

Since this is a massive/breaking/optional change @bd808 thinks that if this should be ever implemented - it should go into Tool labs.

Want to know if there is any consciousness in developing such a thing.
