I think it's rare to see "Reddit" used to refer specifically to a subreddit. The two words are distinct for a reason, after all.
And I have noticed that there is a 1-3 day lag from the front page of HN to the front page of /r/programming+/r/technology. My guess is most of the frequent contributors there see the content here on HN then repost it.
This place really doesn't look so different to r/programming+r/technology.
