|This page in a nutshell: An unfinished article is not a harmless thing. As such you should make it accurate and readable before saving.|
Wikipedia is open to be read by anyone at all times. Google rapidly indexes pages and as soon as someone searches for the topic you're writing about, they will find your article. Real damage can be done if your article isn't ready for prime-time. Too many students have failed tests and assignments because of the inaccuracies of that little stub someone wrote on the topic they were researching (whether they should have been using Wikipedia is another story). This doesn't help people's perception of Wikipedia (think of all the schools and colleges that ban referencing it). Then we have the issue of people getting the wrong ideas about a living person and harming them in the process. All of this impedes our core mission: to inform people about whatever subject they want to learn about. An inaccurate reference resource helps no one do anything except perpetuate the inaccuracy.
Don't put your little substub in the mainspace until it meets the building code. In the mean time, keep it in your userspace as a subpage of your userpage (for example, put it here) until it's ready to be read. Check the zoning laws to make sure your subject even belongs here. Then when you have something useful, move it to the mainspace. It will save you a lot of headaches rather than waiting for your article to be demolished or nuked from high orbit and then having to explain everything to the city officials. In the process you let them take care of the real problems instead of having to work with you and your little building. The Empire State Building wasn't open to the public until it was finished and inspected. Remember, on Wikipedia, finishing means pressing Save and the inspectors can only demolish what's already built.
