This page in a nutshell: In Articles for Deletion or any other Wikipedia discussions, editors should feel free to quote their own essays provided that they do not hold them out as policy or consensus. There do exist reasons not to quote your own essay.

The popularity of essays and information pages on Wikipedia is growing. During articles for deletion discussions, editors may sometimes quote essays and information pages as supportive material for their arguments. From time to time, other enthusiastic editors may point out that the first editor is simply “referencing their own essay” and imply that it is not a valid argument.

Examples:

• Keep I think that this argument should be kept because of WP:EXAMPLE. SelfQuoter 11:54, 3 August 2009 (UTC)[reply]
• Delete You're quoting your own essay, that's not a reason. NoQuoter 01:42, 6 August 2009 (UTC)[reply]

How do they know who wrote the essay, you might ask? It is not a difficult task to check the history of a page and learn who the primary contributors are to that page or article. There are very few "secrets" on Wikipedia!

So what are the reasons both for and against quoting your own essay in a discussion?
