@cda72b9b @53c578bc as I Said in my previous comment, on WordPress they are not calculated at all and 0 by default. If there are other numbers then they were tweaked by blog-owners.
@0c3a0f82 @53c578bc Oh, I thought that those numbers where calculated by fedidb, not self reported by the server software.
@cda72b9b @53c578bc btw. you can find the spec here: http://nodeinfo.diaspora.software/schema.html
