Having just arrived from Reddit, one thing that seems to be missing in Steem are content categories. The front page is one big soup of assorted content (like you'd expect a front page to be), but there doesn't seem to be any way to filter it that I've found. The tag list on the right acts like more of a suggestion than an actual category system, with results often being completely unrelated to the selected tag.
Perhaps I failed to notice a site feature that provides this, or it's something that's still being worked on, but if that's not the case, Steemit could really stand to gain from adding it, because as interesting as the revenue system may be, it's harder to gain mainstream popularity if users don't have the ability to select what content they want to see.
What do you think? Is it easy for you to find the kind of content you're looking for? How do you do it?
