The 20 limit was really based on personal experience in the sense that those are 20 really high fidelity connections with people you know and interact with in a way that's more powerful than the network of 100 interrelated people. So if I have a close friend group of less than 20, in fact more like 12-15, I know that's going to be a tight knit group. Whereas if I open that up to 100, it might be more generically based around some interest like "tech dads" with passive conversation but mostly dominated by the vocal minority. Maybe there's a place for that but I'd be interested to learn and see the limits myself before opening it up. Or just charge for that 100 member group.

I know in a community setting you have more passive members than not. I just don't know if I want to start out enabling that before having really solid admin and moderation tools.
