On the topic of initiative and spolight-sharing (initiative being all about that, in a way), here's a fun thing to do I tried last session(I think it's in the book, but I'm not certain):
You know when a player blows a roll, you're supposed to do a keeper move, right? Don't always inflict it to the PC whose player blowed the roll.
Instead, spring from the fiction and misdirect so what's you're telling comes from the blowed roll, sure, but inflict it on another PC (or a few of them) and ask them what's it they're doing.
That way you're passing the spotlight around in accord with the fiction. Works like a charm.
