What is a good timeframe for "regularly updated"?

I didn't want to hijack but a good point came up that brings up a good question -

When sites start going stale, you'll have massive traffic drop off (primarily search engine referrals) that are difficult to turn around. You'll need regular content and external marketing every week for each site -- with 72 active sites, that's 72 campaigns and articles each week.

So, how often do people consider "regular updates" to keep traffic coming back at a steady pace? A day? Week? Month? Hour? Minute?

I'm sure the more updates, the better but there comes a time when it is too much - there has got to me a happy medium somewhere.

So, where is this time frame?

Thoughts?

This is a good question, which really hinges upon your ultimate goals. Search engines like to see at least a few new posts a week - more if you're going after competitive terms. Make sure the content is original, high quality and reads well. As a baseline, make sure you update at least twice at week, at a minimum.
