From Wikitravel

Avoid first-person pronouns -- "I", "we", "me", "us", "my", "our". Don't refer to yourself as an author -- "the author of this article thinks".

Wikitravel articles, with rare exception, have no single author. Multiple contributors work on the same page, so it becomes confusing to understand who "I" refers to.

You don't need to qualify your opinions with phrases like "I think", "I found", "I enjoyed", "seemed to me", "in my opinion", etc. If you actually think or feel something, plunge forward and just say it. If you're wrong, someone else will correct or modify your statement. See Wikitravel:Neutral point of view for more details on stating opinions.

Exceptions

Some exceptions to this rule should be obvious, but are listed here for completeness.

• When speaking of Wikitravellers as a whole, especially on pages in the Wikitravel: namespace. "Welcome to Wikitravel; we hope you enjoy it" is perfectly OK.
• On talk pages, it of course makes sense to use "I", "my", etc.
• On your own user page, it's perfectly OK to use first-person pronouns to introduce yourself.
