100% agree, everything built on/for Steem looks like it jumped out of a kids cartoon! Even Steem-Engine. Me being totally clueless about developing anything at all, I can't force myself to think that the devs suck in designing UI and such. Perhaps, the languages that are used to code for Steem, dont mix with designs that look better that a cartoon?

Perhaps the lack of mobile apps comes from the same problem, that its not that easy, using the tools available?
