Not all lurkers are like that(not really disagreeing with you though) I would consider myself to be a lurker because i only occasionally comment and even more rarely.post. I rarely comment because i know my wording can be a bit weird so most people don't get it at the first read and somtimes I'm not up for a discussion. I also rarely post because i don't know if that specific thing is worth posting or i just don't know how i think about the topic or something weird
