I get the point, but as I mentioned it all comes down to how the system works.

Svven for example puts together people tweeting same links. Tweeting, not liking. Two tweets containing same link can have very different and often contradictory messages.

To give a practical example, some of you probably noticed PG's controversial tweet about unions (https://twitter.com/paulg/status/663456748494127104), and also the reply that took double the likes of that (https://twitter.com/MarkAmesExiled/status/663495439069614080). Because the reply contained the link to PG's tweet, in Svven you can see all sides of this story around the same link.
