One idea I had is for producing some simple infographics and videos on the topic. But when talking about the STEEM blockchain, do NOT give SteemIt any special attention. Just mention it along with all of the other great STEEM projects, like D.Tube, Vimm. SteemPeak, Busy.org, etc. In fact, just treat it as something that is equal in base design as Busy or SteemPeak.
The other thing that would help is maybe have a very simple icon made that links back to some site about Steem, though I don't know which would be the best to link to. But the icon would have the STEEM logo and the words "Part Of The STEEM Network", or something like this:
In this way, sites using and utilizing the STEEM blockchain can show that they are using it, while differentiating the fact that it's NOT SteemIt. This is especially important that SteemIt place this logo front and center on the site to make it clear that they use the STEEM blockchain, not that they are the STEEM blockchain.
There's other issues besides this though. The official Wikipedia entry for "STEEM" links to SteemIt, not Steem, and seems to offer that's there's no difference between the two.
The STEEM community can tackle this issue in multiple ways, and I honestly think we should all do our honest part to try and promote the STEEM blockchain proper, instead of just SteemIt. Heck, SteemIt isn't the top dog anymore for using the STEEM blockchain. I'd say that award goes to either @SteemPeak or Busy.org win that award! (SteemPeak is what I use and adore!) If developers and users of the STEEM blockchain take steps to always give credit to the STEEM Blockchain instead of SteemIt the blogging/social media site, then we could help to slowly clear up these confusions.
