was considering transferring here but I see literally no difference.

It's a website, not a marriage or political party. You don't have to choose just one, you're free to use both, one or the other, or none. I think many people here probably use both.

I go to Reddit for some small niche subreddits and things I still enjoy there, but the frontpage and default subreddit stuff has gotten pretty bad there. Like others have said, there's very little sense of community on Reddit anymore. It's too large. As a result, people don't care if they tell someone off, people don't care if they just troll, people don't care if they just repost crap or memes. Personally, I'm not into all the circlejerky stuff there, or memes, or another story about how someone lost 50lbs, or found a cat, or looking for sympathy because a family member has cancer and they want upvotes for posting their picture. Sure, you can get away from that in the smaller subreddits, but that stuff still even happens in some of those. That's kind of the "bulk" of Reddit these days, and I don't enjoy those aspects of it anymore. But I do enjoy that it has farrrrr more content than Hubski, I enjoy that there is a niche subreddit for everything, like ecigs, buddhism, IT sys admins, lawncare, home owners, etc. That's what I like about Reddit. There's a lot of general topics here, but nothing getting down to that granule of a level. The community just isn't large enough yet, and while that is a weakness in some aspects of content, it's a huge strength as far as community.

Here, like everyone has already said, it's a small community. When there are discussions, I actually recognize the people, I know what states/cities most of them live in, I know a little bit about them and their opinions. People like thenewgreen even go as far to give me a shout out when they post something about SpaceX or Elon Musk because they know I'm into space stuff. It's things like this that make Hubski great.

So use whichever you want, or just use both like many of us. :)
