I tend to post more when things flare up.
It seems there's a solid core of people who have known each other for years, and many people are kind enough to offer suggestions when asked.
I don't really comment on things I know nothing about, or on long-standing threads among friends. Feels like crashing someone else's party. To me, anyway. I'm not upset about it, I just don't want to stomp my clumsy self through good friends chatting.
Also, I work full time. Spouse, teenagers still at home, dog, cat, insurance denial to appeal, so on and so forth.
I don't have the time to be very active online. Unless I'm sick in bed.
And my crohn's has been relatively mild so far, so I don't have experience with some of the subjects discussed.
