Not really. Steemit.com does not integrate. Yes you can see the post and hit the like button. But that's not integration. Integration means they work flawlessly in place and display all relevant information.
p.s. Steemit.com can go down and everything else will keep working. RC can be bought from the blockchain by the dapps on behalf of their users while they use a token.
