I think everything right now is still speculation, since hubski is still young and small. But as the other posters wrote, over time some migration will happen and of course new users will follow, too. But as someone in another thread put it: I wouldn't say reddit and this website are competing, they just co-exist right now and seem to have (at the moment) some minor differences here and there, which - in my opinion or how I see it - will grow over time and both will get more and more diverse. I see it a bit like a forking process in software development: habski split from reddit (the general idea behind it) as a branch, and as time goes on, both will get more unique and their own identity.
We like to emphasize that there is no competition between the two sites, because it's something that comes up far too often. Yes, both sites are aggregates where you can submit and comment, but that's about it. The philosophical differences are huge, as are the more subtle mechanical differences between Hubski and Reddit. The internet is a huge place, with more than enough room for both websites.
| I see it a bit like a forking process in software development: habski split from reddit (the general idea behind it) as a branch,| As a bit of trivia, Hubski's actual DNA is actually a lot closer to Hacker News than Reddit. Hubski started with a modified HN code base, though you'd never be able to guess looking at the two sites side by side today, mk has transformed the UI so radically that there are very few visual cues left. On a conceptual level though, I totally take you point, though I think the Hubsi and HN are still closer relatives conceptually as well...thoughtful discussion and all that :)
