A friend of mine pointed out, that it would be nicer if the date would be visible on the cards when looking at an overview. Now looking at https://blog.ghost.org/ I totally agree with him. It would be great to see at one glance, when each post was published so that I can get a feeling, if I missed reading something, or how up to date some information might be.
He provided the following screenshot of an example on how it could look like:
Although, I see now, that his date format is too long for some of the publishers on https://blog.ghost.org/ it could be reduced to just dd.MM.yy or MM/dd/yy or what ever you prefer.
