The concept of SMT is fairly rigid, and as i tend to see here on Steemit, it really does make for better curation then just plain 'like' or 'heart'
SMT's create neccessary value for the content, but also make people ask themself twice about why and when they give their STD or SMT to another person.
BECAUSE there is actual monetary value to it. Inthe end, my guess is that this system wkill perform way better for quality curation and stuff.

I LIKE :)
