No worries on sidetracking, I've been really curious about SMT's as well. It almost seems like everything could be done with steem. Maybe when other companies come in they will want their own tokens and maybe they can perform different functions.
I'd love to see a more configurable layout as well. Like even separating resteems and user blog posts on a persons blog page would be really nice. Or muting resteems from certain users. Having a tab for different content like zappl etc. All that would make this platform incredible. I'm sure doing that would be a challenge for devs, but worthwhile imo.
