Microblogging is like Twitter while Magazines are more like reddit. There is something to be said for supporting both on one platform.
I also found kbin harder to get around at first, but I got used to it before long. It's also pretty new and is evolving quickly. Some of the UI issues look more like the results of an incomplete feature set rather than bad UI design. I suspect it will make more sense as it fills in and matures.
And if you just don't find it comfortable you can always try a Lemmy instance instead. It is further along in its development and has more of a reddit-type UI.
