Sometimes, yes. On this forum I sometimes write a post, but then I feel like I've shared too many details about myself or that I didn't know how to express my opinion with words. On FaceBook I never write anything besides birthday congratulations to my "friends", and that's because I don't think I have anything interesting to share and I know I'll meet the people in real life later. On YouTube, I never hesitate to write what I think about something. Right now I'm telling aggressive commenters to stop spreading hate, and that results in a lot of negative reactions, but I don't care.
