It's no frills, just works, saves a cached version of the page when you bookmarked it, doesn't change in any way that is going to surprise you, did I say it just works?
I've wondered the same.. I actually subscribed to see what the hype was about; after using it for a few weeks I found it hard to justify the cost for such a simple and relatively featureless webapp
I only paid one up-front fee of about $10.00. It isn't subscription-based. That is stated quite clearly on the home page. Be sure you go to http://pinboard.in/ and not one of their rivals.
I'm Hungarian and I can assure that this move is a beautiful temporization from our government. They proposed this tax to herd the attention from the 'banning scandal'.[1] And now from one moment to the other, they are heroes.

That's a thing I have been thinking about for ages.
Curently it works like this:
- Someone adds an opinion (they show their support for the viewpoint -> the viewpoint gets a +1)
- Someone votes on an opinion (they show that they like/dislike the opinion not necessarily the viewpoint -> the count stays the same)
I love the interface and structure.The loading went really really slowly though.
I would suggest you to add some keyboard shortcuts (like [J] and [K] for switching articles back and forth) and let the users participate!
