You can post rubbish about celebrities and politicians and get your audience to argue about it because your audience is so far away from the corridors of power that these people are just cartoon figures to them, and indeed to you. Politics as WWF match compete with a masked villain.
It’s a very different thing to post personal spite about participants in a small hobby world, because many in your audience will know these people IRL (or even be those people) and be personally offended. Then if you delete their comments because they attack you personally, you are destroying the lifeblood of a blog, which is the community it creates among participants.
DHub has lost the plot as far as running a “controversial” blog.
Of course I don’t believe that was the original model. The original DHub was meant to be a news and promo site for Florida and national dressage, with content from DHub’s coach at the time. Lots of her online followers date from that time.
When that relationship went sideways, DHub started to use the existing platform to try to taunt and humiliate her former coach, and burned her bridges in Florida.
So there was never a plan to develop a controversial or provocateur persona. It’s just been train wreck of interpersonal spite since the original plan went off the rails.
