I think part of this comes from wanting a broader base of content, which I agree with. The rest seems to come from wanting the downfall of Reddit, who is in my rearview mirror so I don’t care.
We are currently like old Reddit, a techy, mostly progressive, crowd. That means a lot of uni-topic content.
When there are 10,000 users, and 5 of them are into sewing, the sewing community is dead. When there are 100,000 users, and thus 50 interested in sewing, content starts to form. You can see where this goes from here.
