As far as the latest version of Pinboard goes, the following css worked for me, removing just the date and author and keeping Edit and Category links intact:

.entry-author-link, .entry-date {
visibility: hidden;
}

“display: none” wouldn’t do it for some reason.

This is the code that worked for me on Pinboard (removes author name):

body .entry-meta .entry-author-link {
display: none;
}
