Tropes listed in the Wiki Tropes index are being discussed at the Trope Repair Shop. Click the link here to join the discussion.
If you suggest a trope which is basically just an excuse for discussion and listing your favorite or least favorite moments, series, and characters, you might be told to Take It To The Forums. Which are these. The tourist guide can be found here, and the detailed map for intrepid explorers is over thisaway. If you have gotten known, you are already a signed-up member.
The wiki itself is not a place for random discussion. To be a trope, something has to be measurable, its examples meeting a certain fixed definition rather than depending on the whims of the tropers who add them. "I like it/I don't like it" doesn't meet that standard. Although several tropes of this variety have been deemed worthwhile enough to slip through that net (or have been grandfathered in from the pre-forums era), it'll be an uphill climb to convince the Hive Mind that we need another, and you'll probably be told to take it to the forums at least once.
That's what they're there for, after all — they're a place for tropers to discuss the things that don't really fit into the scope of the wiki proper. You'll like them; we promise.
