I find community proliferation like this very entertaining. People learn to identify so well with one community or its content, that they replicate it inside other communities. For example, I was bemused recently to learn that Reddit has an r/4chan. I asked, "Wouldn't you just go to 4chan?" But they found it more moderate, more suited to a Reddit user's taste.
The existence of r/4chan is met with scorn every time I've seen it mentioned on 4chan. People seem to either completely hate Reddit itself, or meekly admit that they follow a few tiny subreddits. Given that (and the response you received to your question), it would seem that r/4chan is composed entirely of people who don't actually browse 4chan! One has to wonder what proportion of these members of the "Hacker News Google+" community actually participate on HN.
The more I think about it, the more strange the existence of these offshoots seems: The average 4chan user hates Reddit, and the average HN user seems to not care much for Google+, either (though I'm not sure if that has more to do with its community or the way Google is currently shoving it into everyone's faces).

Non-sequitur (really a classic syllogistic fallacy if you consider who does the scorning). Peer pressure exists ('meekly admit'). One could even imagine that the kind of 4chan user who might prefer to sometimes express themselves in a more 'moderate' environment such as on Reddit would be the kind least likely to provoke a visceral response by outing themselves as a user of r/4chan.
It's very difficult to know anything about the 'average' member of an online community, especially without surveys.
The HN format is only good at a few things. It can't do things like images, or adding commentary to links (I mean as part of the OP). There are other things it's not so good at, like linking to all of a user's posts and comments, showing real names of users, searching by topic, resharing to people not in the HN crowd, etc.
I agree on both points. Sometimes its just nice to go to one place and have all sort of interesting discussion. Reddit is a very good place for that. On the other hand, community efforts are unnecessarily divided.
To each their own, eh?
