Generally speaking, you can release based on the calendar or based on whenever you think the feature set warrants it. You are advocating the latter which works well on low traffic projects. The former is a better idea on high traffic projects where there's always something worth shipping whether it's a new translation, a bug fix, or new feature.

It depends on the project, but in larger projects the calendar approach means politics takes a back seat as no one can hold back the release if their feature hasn't been merged yet due to blocking issues. And it helps keep the change-set small, and hence lower risk, if you release more often.

Also, Firefox already has a nightly release stream. I use the Aurora stream which releases a few times a week and have almost never had an issue with this frequency. I don't think a monthly release cycle is going to be an issue.
