"is he saying it’s my fault that I feel left out"

Yes, and no. I was just saying that I hang out on m.b more and butt into conversations more.

My own interests, it does not fully cater to. I do NOT talk to anyone online about coding. I'm just not that kind of person. I do want to talk about philosophy, reading, Tintin, but I won't. It's too much work.

So I'm just chilling on m.b and going with the flow, but I am spending a lot of time on there.

Not expecting you to do that. That's not feasible for everyone, and on days (and weeks) when I'm busy, I couldn't be bothered to go there.
