I'm aware of this difference and I never used Steemit as an frontend - always preferred busy.org and other apps. My critique is actually on both or to be more concrete on Steemit Inc who is responsible for both. Some points like the 13 week power down concern also both at the moment. Since there is no way to clearly filter content from different apps, this is also an issue concerning both. SMTs may fix some of these issues, but again, this is only a fix needed already for a long time and no innovation.
