I personally don't think it matters much at all, except in channels that specifically identify that way. However, I am male, hetero, cis, so its possible I'm just clueless.
Depends on context, as always. A user sharing a story on social interaction, gender may be quite important to how they experienced it and how others perceive it. I.e., a post the other day asking about worst dates and the average worst date for men was a woman on coke or a no show. The average worst date for women was about getting sexually assaulted or raped.
Men are victims of those things too and can face different repercussions when they try to pursue help. Understanding their experiences within the context of them being men is also important.
Stripping gender from these stories only obfuscates some of the problems.
