Two of Ireland Information Guide's rules to consider
Both of these guidelines are controversial.
Contribute what you know or are willing to learn about, but create stubs responsibly. One of the things that makes the Ireland Information Guide great is that anybody can contribute. Another thing that makes it great is that it encourages Ireland Information Guide users to stretch their interests and learn about new things, so that they can add to the 'pedia. A third great thing is that it's so easy to create new articles and to learn to wikify articles. The ease with which new articles can be created, however, can be seen as problematic when users get into "creation mode" and create more stubs than coherent articles. This can even be irritating, if the stub is accompanied by a "I don't know much about this--would someone who does please write the article?" message. So, if you can't create a stub that's accurate and helpful, maybe you should leave that topic for someone else to do by choice, rather than because they feel obligated to edit.
(an alternative phrasing)
Whenever you create a new article, always try to make it as complete and comprehensive as possible. However, an article that is seriously incomplete but a useful start is welcome, too. Don't create a new article that has fewer than two sentences, or people viewing the article may be disappointed. If you have only one sentence to contribute, consider adding it to a relevant existing article instead of creating a new one. If you are a newcomer to Ireland Information Guide, concentrate on adding good content; do not worry too much about formatting.
