Some channels don't like it when you switch nicks a lot. If you want to part those channels to cycle through your nicks and mess with their access lists or check their memos (or whatever), /part -n would be a wonderful way to avoid getting kicked for nick flooding and you could simply /hop to rejoin after you're done. No lost buffer - no pissed off ops.
