Using logs as a debugging tool is only step one. The second step is using a good tool that helps you make sense of those logs, and includes good debugging information with the logs. A tool like Rollbar (disclaimer: I almost work for Rollbar) makes it super easy to analyze patterns in your errors and logging, find out who experienced the error, and to hear about the bugs before your customer, who may have become used to them. Anecdote from my previous employer: we had a terrible piece of legacy software that regularly had modal pop-ups warning of errors this or that that doubled the amount of time our clients took to do stuff. They were so used to it that instead of reporting the error, they just dismissed them.
