I maintain at least one reasonably large open source project myself and pride myself on our turnaround time.
Our users/contributors don't need to wait weeks, months or even years until their issue is categorized, addressed and resolved.
Of course part of this is staffing and domain dependent, but I do believe that marginal updates to a project (< once per week) is worse than quitting
Good for you. I have a life, and will never hold myself to such a standard. It's a side project I decided to give away for free. People can wait as long as it takes.
No one owes you anything. Even if they committed the sin of making a website for the project.
