I like the HackerNews or Reddit direction more than the the Twitteresq direction.
The thing is, everything from (hash-)tags to subs is a spectrum. Mechanisms can separate or connect the communities as much as one wants.
I agree.
The thing is if SN opts to be in the middle of that spectrum it can end up being a poorer version of both reddit and twitter, failing due to its own indecision.
