Issue isn't sexiness, it's functionality. It UX as a whole. DMs are broken on most clients. Reliability is low. WoT doesn't seem to actually be used in any meaninful way, discovery is difficult. Most clients have zero built-in filtering, making your global feed a venture in dangerous territory. I shouldn't have to tell my client to hide posts with the n word, 90% of users want this hidden by default, as a very basic example.
