for some reason it's not catching on with me.

Can you elaborate on this? Even if it's hard to pin down specifics, I would be great to hear why you feel this way.

Compared to Reddit, Hubski is currently a quieter, more intimate place. This has benefits and drawbacks. I would love to see more fragmented communities here, but I've come to believe that some dynamics require a certain mass of users. I have definitely seen posts and interactions become possible here that weren't in the past, but as zonk mentions, we aren't yet large enough to sustain most niche communities.

We continue to grow, and I look forward to some of the possibilities that come with an expanding user base. However, at this current size, there are some limitations to what Hubski can be.

That said, feel free to try to make Hubski what you would like it to be. Use the following mechanisms as you would like to. Unfollow everyone (there is a button on the bottom of your profile page) and build a new feed every month or so. Follow only tags and domains, or follow only personal tags. Limit posts to one sentence. Whatever you like.

I should say that we (mostly forwardslash) are currently rewriting the entire site from the ground up. We have a plans for the future, and have concluded that the best path there is to build with tools that are optimized for it. That's not to say that Hubski is going to be significantly different, but it will do what it does a whole lot better.
