My sense, and maybe I'm off base, but as someone who's been here since the beginning - I don't think the founders of this site are Not Paying Attention. They are, for the most part, not posting frequently because, well, they don't have to. You have the ability to limit who sees your posts and those people who find you can also limit what you see in return. That goes a long, long way towards making sure people feel safe posting content.

Over in my corner of DW, I haven't been exposed to the mass insanity that other social media sites seem prone to - but I also don't go seeking it out here, either. What I suggest to you, then, is to see how active you'll be here, what kind of people connect to you and so forth - and then decide whether you want to upgrade and support it.
