one who lives by the credo "Comment Early, Comment Often" on social websites such as facebook. A CECOphile's comments make up an disproportionately high percentage of initial comments and follow-up comments, and are motivated by the desire to be heard and to be viewed as an authority.
Nobody can post to that facebook group without that CECOphile jumping in and trying to own the conversation. I'm inclined to quit the group, but I like to know when he's going to be at an event so that I can avoid it.
