I don't know if this is the right meta for this discussion or not, but as it might relate to some other folks with strong Sabbath-keeping beliefs, I thought I'd start it here.
I just obtained the Enthusiast silver badge for logging in for 30 straight days. On C.SE, this is no issue with respect to my beliefs, because I regard what I do on C.SE as in concert with Sabbath-keeping. However, C.SE is the only SE site that I can, in good conscience, log into on the Sabbath. All the others are work-related, to my mind, such that I cannot log into them on the Sabbath. Therefore, the Enthusiast and Fanatic badges are currently unavailable to me on any other SE site. I like SE, and I view the acquisition of these badges as a vote of confidence in SE sites.
I propose a modification to the Enthusiast and Fanatic badges as follows, in order to accommodate folks like me: these two badges still require 30 and 100 "consecutive" logins, but those logins can be interrupted by a regular, one-day-in-seven day with no login. The "regular" nature of the interruption would be necessary, I think, to preserve the respect due to the badge, and also because the vast majority of people would celebrate the Sabbath on the same day each week. So this could be an option somewhere in your settings, perhaps, so that you could specify which day of the seven you're not going to log in. And it's not that SE would prevent you from logging in - it just means that the "consecutive day" counter wouldn't reset on that day.
I recognize that this might mean a significant modification to the SE software, but it would make the software more meaningful to me, at least, and I think to others as well.
