It's a social signal. You don't want people to criticize your fun weekend hack because it hasn't demonstrated product-market fit, or because it doesn't stand up to the market leaders, or whatever. Without a clear label, every time someone coughs around here it's interpreted as some kind of business plan, or an attempt to get into YC. The title tells you that this submission is for fun. Either try to look like you're enjoying yourself when you read it, or take note of the warning label and skip the article.
