Yes it's an odd one that, in fact the whole calling things names like faecesbook, wendyball etc, which I assume are supposed to be simultaneously humorous and convey your disdain and superiority.
Twitter is such a diverse platform that it strikes me as being a bit daft to write it off entirely, there's every type of person imaginable on there, and everyone is free to pick and choose. It's a bit like here in that there's such an assortment of people and views, but I can't think I've ever seen someone call this Cycle Twat cos there's some bits you don't like.
As ever I think it tends to be ignorance and prejudice triumphing over the more complex reality.
For instance on Instagram I follow cyclists, farmers, dye makers, artists, horseriders, meteorologists, feminists, gardeners, activists, poets, philosophers, cooks, mountaineers, musicians, politicians, geologists, select family and friends, and plenty more besides.
No trout pouts, no buff guys flexing.
Despite that being what it's habitually written off as being all about, by people who clearly have no idea.
I've discovered fascinating things, places, and people on there.
Like here it's a cross section, and you can ignore stuff you don't like..
