Some people have the need of constantly thinking on terms of zero sum. Take for example the "Steemit vs. BitShares" post.
In reality Steemit has emerged from Bitshares, therefore in the long run both projects will benefit from each other. The Steemit success will help to grow awareness on Bitshares and by the way the Bitshares trading platform is the most logical way to capitalize some earned Steem.
So I tend to view both communities as somehow on the same boat. If Steemit fails, then it will hit BitShares, but if Steemit suceeds it will also benefit BitShares.
