What level of conversation is Tildes aiming for?

One thing I'm uncertain about Tildes is how informative its posts are meant to be. I've been keeping myself from posting hype threads about upcoming movies (Dune, Ride Your Wave, etc.).
What type of balance is tildes trying to strike? I'm in favor of shitposting, but against images, since I think text encourages the type of discussion I'm looking for a community. So I'd like to see copypasta, but I'm not sure what the general consensus is.

Edit: I'm looking less for general examples than some sort of hard and clear rule. I'm seeing comments which disagree somewhat and leave ambiguities, but I believe the criteria should be better laid out.
