Hmm. For someone doing horsey business in the Southern half of the USA, it doesn’t matter that much if COTH has truly international reach. It matters whether it’s being read in Florida and California.
My sense is that COTH the publication and the forums trend more to English sporthorse disciplines and hunters. Less to breed shows. So if you were embedded in say Arab circuit you might pay less attention. But jumper, dressage, eventing are more likely to follow it.
Also just because you are not internet savvy or don’t follow a given platform doesn’t mean no one else does. That would be like me dismissing TikTok as a social force because I don’t follow it or really like it.
But what really matters is what comes up when you Google.
