Well smt traffic and steemit website will be two different types of traffic as steemit is website related and smt is blockchain related, so the two are mostly independent right?

We don't know that yet. My hunch is that steemit.com will continue to show all the content saved to it and the wallet will contain all the potential SMTs. So a drastic increase in traffic can come from any part: the separated sites of the SMT-powered community, or Steemit.com (via search engines, etc).
