I have launched several side projects a couple of them financially successful. They have had plenty of bugs in them and I got several angry emails about various things, but over the time I have fixed them as they come in. It's a great way of prioritizing what of that last 20% you should fix. In other words. Ship as fast as possible, treat it as a project then over time improve. If you have something of value people will use it even when it's not optimal.
