We Are Not Alone Index

In short, tropes which have Wikipedia articles. In long:

Here on All The Tropes, just as on The Other Tropes Wiki, we tropers dedicate ourselves to cataloging recurrent patterns in fiction. Everyone knows that; it's the name of the game. Other sites deal with tropes, too, though none of them are as exhaustive as we are, which is perfectly normal. However, there's one site that takes it too far: it's supposed to a free world-class encyclopedia, yet it's wasting time talking on and on about cliches in fiction. And that's our job. Isn't that a waste of bandwidth? Perhaps so, but the practice is a lot more common than non-tropers would think.

The truth of the matter is Wikipedians do it for a variety of reasons—the Trope may be common enough for scholarly interest, it may say something about psychology, or it may simply just be one of those many Silly Things Wikipedia does. On the other hand, it might also be because our two Tropes wikis have fallen victim to the Law of Wiki Expansion, and the topic really is one that best fits in a general-interest encyclopedia. In any case, it's beneficial to both All The Tropes and TV Tropes; the more pages on tropes there are on Wikipedia, the more people will be led to our sites.

Not to be confused with You Are Not Alone, or the idea of other intelligent life in the galaxy.
