I don't remember where exactly I found this advice, although I continually find myself reminded of it anytime I review satistics, and even most of the times when I zap:

If you're simply here for the community, disable zap notifications;

and I emphasize further, the advice was to disable, rather than raising the minimum threshhold for notification.

I've been keeping my notifications for zaps enabled, because I'm still studying my own anecdotal experience in obsessive detail while wondering about the various "user stories" that approximate the typical behaviors; however, by actually disabling all zap notifications, you actually give way for notifications to help you carry on your conversations with the community; and if you're ever curious about the zappy moderation metadata, you can visit satistics or just mouseover the word "sats" in the leading line of the relevant comment.
