I've seen a race of electronically linked humanoids who share information in a vast decentralized net to which they all have access; who see data as a kind of neutral atmosphere, like air; who use technology to share thoughts and impressions at all times; who are never out of contact with one another; and who react to the briefest removal from their shared consciousness with an itchy, frantic eagerness (cf. "Hugh") to get back.
Tropes are devices and conventions that a writer can reasonably rely on as being present in the audience members' minds and expectations. On the whole, tropes are not clichés. The word clichéd means "stereotyped and trite." In other words, dull and uninteresting. We are not looking for dull and uninteresting entries. We are here to recognize tropes and play with them, not to make fun of them.
