Which themes use internal tags to sort posts?

Does someone know which free standard themes use internal tags to sort the ‘maybe you like this’ kind of thing. I got a list of the themes but I lost it. Trial and error with the new default theme make me think that one doesn’t but which ones do?

I now know the answer to this question:




These three free themes sort related posts using internal tags which is a brilliant way to make people aware of complete other content and older posts on the site. I really wish Source did too, since it is a very nice looking theme. Especially when reading and scrolling through it on a phone.
