Using your product daily is essential not only to help steer the ship on what to build but also to cue you in on what's buggy / inefficient. I have the good fortune of having a live chat interface (product is: https://www.jqbx.fm https://www.jqbx.fm) so I get pretty quick feedback if something that's been pushed is causing anyone any issues. However to keep bugs to a minimum I keep most of the logic client side and have a dev environment that I can run on production- I usually test a version for a couple days (see: eat your own dogfood) before releasing anything. Also forcing yourself to review your own code is a good skill and has helped catch some issues right before pulling the trigger.
