Well the content is already there, it’s actually the tools to make it easy to use. I think the devs are to blame. Both medium and reddit allow you to follow topics. In medium you usually only follow devs, because barriers to writing are so high so it’s easier to make a stream you want. Follow the devs of maker or zrx or similiar and you’ll get a stream of stories that are relevant.

Perhaps all that’s needed for steam is multiple groups of followers. Let me follow devs on one tab and commenters on another. I think just organizing them into groups (communities) would help a lot. Also in medium you get suggestions about things you like. This is much easier to discover good content than on steemit.
