At first it was all about presenting data in an original looking way. In the end it was about pushing political ideas in your throat using a plain bar graph. It was not about sharing something interesting you found but about taking advantage of a captive audience.
Men’s spaces are good for emotional support for men who are not able to get enough support in their everyday lives. It’s better to be getting support from other men than to expect all the conversations about feelings to happen with a girlfriend or wife, especially when the guy is single, or in a relationship with another guy. There is, naturally, some discussion about women, some involving hurt feelings, which can skate towards misogyny. But a whole lot of serious discussions go pages and pages without mentioning a woman once, positively or negatively. If the whole space is full of posts about hating women, it loses its value for men who want to talk about themselves, not women.
If you’re not interested, then it’s not for you, no prob, but a lot of guys find it extremely helpful.
