Well when it boiled down to it in the end I was mostly interested in /r/askreddit, /r/iama, /r/casualiama. Pretty much the flavor of this site.
From the limited bit of hubski I've seen it should be a good fit. In a lot of ways hubski is more like the stated goals of the true* subreddits, trying to foster discussion over epeening. And you'll never find as good a place for the cool images as reddit, it's just hit the critical mass to keep rolling. One important thing to remember about hubski is that it's not nearly as time sensitive as reddit is. I've seen threads here that have been active for weeks, while on reddit if the thread is older than an hour it's probably not worth participating in.
I'm not sure if this has been mentioned in any of the welcome posts or responses to questions, but on Hubski it's even encouraged to participate in older posts. People comment in posts that are weeks to months old and it can generate new discussion. So please, if you see an old post that you find interesting, feel free to comment in it. At the very least it will show up on the chatter page and maybe people will find it from there.One important thing to remember about hubski is that it's not nearly as time sensitive as reddit is.

When 4channers started leaving for 8chan a commenter on a thread complained about that same thing. OP reminded that it wasn't 4chan so the replies don't flow as fast. I get it.
