It really doesn't, but it's up to us to change that mentality. I write the same way, talking about stories within larger stories. However, I still do risk posting my longer work in here. While there's currently not that many feedback on it, there are still some awesome readers who have enough patience to read longer pieces. It's up to us to dictate what the platform is capable of. By supporting one another through commenting on each others' work, other people would feel inclined to do the same. I truly believe that.
