ah wait, so users share content from other sites onto Steem? And Dlike creates a new post with the metadata it scraps from the other sites?

I initially thought it was just about pinning existing Steem content on to a nice UI.

hmmm, looks like the app is just trying to making copy/paste acceptable.

So this:
https://dlike.io/post/tophash/extreme-smores-milkshakes-recipe-peanut-butter-milkshake-milkshake-and-fudge

Becomes this in the blockchain:
https://steemit.com/dlike/@tophash/extreme-smores-milkshakes-recipe-peanut-butter-milkshake-milkshake-and-fudge

Don't we have enough stuffs like that already?

You’re pretty much spot on.

This is a recipe for disaster, we are already doing our best to eliminate content like this, steemcleaners will flag for this kind of content it's copy paste and takes no effort :(

I think the idea behind this is similar to Pinterest, collecting and sharing. Finding people with similar interest.

If it was only pinning Steem posts then it would have been good. But this is different, you can pin Steem post but you also pin say a news article from another website and it creates a Steem Post with a photo and couple of lines about the pinned article. Basically it is creating content with no value on the Steem blockchain
