Hari Om, @julianhorack, steemit.com is a blogging platform on steem blockchain. Thus it is for blogging and not for sharing links.
Dlike.io intends to follow the Pinterest model, where you share links and bookmark them.
Likewise on steem blockchain they have for Facebook, @steempeak, @partinko and @steeve, for Twitter, @zappl, for Youtube, @dtube, for crowdfunding, @fundition, for food blog, @tasteem, for photos, @steepshot, for music, @dsound, for reddit.com, musing.io, stackoverflow for Science, Technology etc, stemq.io and so on.
Therefore, I don't see anything wrong in what dlike.io is doing except that I don't see quality content on it as yet, probably because it is still new and not many people know about it.
