Default email digest frequency?

The kind of forum I am starting is quite specialized low volume and users will certainly find emails ever 2 weeks irritating.

Can you explain why low volume means the digests will be annoying? For low activity sites, the digest seems like a useful feature since people aren’t likely to visit every day and might stop visiting altogether. The digest should give them a reason to come back. Without it, your community would become abandoned, wouldn’t it? The digest will only be sent when there’s something worth telling people about, with a minimum of 2 weeks in between each email (if you set it that way).
