Email digests

Can I add my vote for an email digest feature? I know that RSS is the future..blah..but right now many many (ie most) people are only just learning how to get the best out of their basic email systems, let alone working out how to download RSS clients and the like.
A simple templated digest feature (HTML and/or txt) which readers could subscribe to in order to receive a week/month/etc worth of posts would be brill IMHO. ??
