When someone edits a wiki page, Phabricator currently sends emails with this content:
USER edited the document content.
This is usually not enough for the user to decide whether the change is interesting enough, whether they should click on the link or not. Both the edit-note as well as the actual changes are missing in this email. Thus this kind of email is regarded by users as effectively spam: It comes in large quantities and contains almost no information.
For pages being created, however, Phabricator emails contain this information:
USER created this document.
It would be great if the email could include the edit-note as well as the actual diff, along with a link to the diff on the webpage, so one could see immediately what the change was about. Or at least include a diffstat, so one could destinguish a small from a big change.
