Actually, my experience is the opposite: mailing lists are incredibly time consuming, because there are a few participants who feel the need to repeat themselves over and over again in any given discussion, and people aren't concise in their responses, nor considerate of the burden their responses will impose on readers, so there is a lot of reading, much of which is completely redundant. Being restricted to the low shared bandwidth of voice in an online meeting substantially mitigates that, if the working group chair is doing a good job of disciplining the discussion. There is a reason why we do f2f meetings, and it's not because we like the cookies (although we do).
