I've been here for like 9 months or so. I like the people here, and I like the quality of content and discussion better. It's also interesting how following people leads to more content that I wouldn't otherwise see on Reddit where I just subscribe to certain topics (subreddits). Here, it's more about the users, and when I follow them, I get to see things they find interesting that I might not otherwise read, which is good and helps me be more open minded.
Reddit, because of it's insanely large population, is still better for niche topics, because even niche topics on Reddit have fairly large subreddits. Like on Reddit I still go to the electronic_cigarette subreddit, the space subreddit, the watches subreddit, and a few other topics that simply aren't represented on Hubski, yet. But at the same time, that large population of Reddit, combined with a point system, has ruined most of the communities there. You're more likely to see a "I DID NAZI THAT COMING" type comment in a thread about WWII history than you are anything informative or helpful. It's all just jokes, and puns, and reaction gifs now.
Hubski is just smaller, fresher, and the sense of community here is a lot better. It's like going to a small college of 1,000 people, instead of a huge state University with 80,000 people. You're more likely to see people you recognize discussing things in threads, instead of just a bunch of faceless randoms you've never chatted with before. I like that.
