Yes, this always bugs me. I think most people are set in the "centralized" mindset and see that Steemit is an alternative the Reddit and it must be the only site that serves the content.
I feel more posts like this in Trending will help break this trend.
I don't think that the Steemit site does much justice for the Steem platform either. Its "Welcome" page is a solid example: https://steemit.com/welcome
I think that Steemit Inc. is undermining the platform they have built on and causing a "Tunnel Vision" for Steemit.com in consistently referencing "Steem" as "Steemit" in all of their documentation.
