i lurk when I have nothing more to add to a conversation, or I'm just too tired to type. Sometimes I'll type something and not send it. But more often than not, I tend to speak up. For one, it helps me keep my place (ha!) and for two, it helps me benefit more when I can feel engaged in a topic. Sometimes I'm cool with just posting and having folks read, but most of the time I'd rather have the feedback. (this time I do not NEED the feedback, but always feel welcome to comment <3 )
