My watchlist is polluted with "diff" links such as https://www.mediawiki.org/w/index.php?title=Talk:How_to_contribute&curid=0&diff=0&oldid=0 . This makes talks entirely impossible to follow within normal wiki workflows (i.e. watchlist).

https://www.mediawiki.org/w/index.php?limit=50&tagfilter=&title=Special%3AContributions&contribs=user&target=Jogi+don&namespace=1&tagfilter=&year=2015&month=-1 provides a different link for the (seemingly) same event: https://www.mediawiki.org/w/index.php?title=Talk:How_to_contribute&action=compare-header-revisions&header_newRevision=srzio7j6hockv0jl
