How long between posts?

BUFFALO, NEW YORK: SUNY professor Alex Halavais became curious and looked at two weeks of weblogs.com ping data. First impression: "it is interesting to see that folks tend to keep their blogs--at least those pinging weblogs over two weeks--pretty much up to date." Just eyeballing the chart, it looks like a median of around three days. Fruitful area for more research: lots of data, including the blo.gs ping server, and opportunities to surf pingers for more information. Do infrequent posters write longer? Geographic or language differences? Correllation with dial-up vs. always-on? Tool/hosting preferences? Use of RSS news readers? Can you provoke infrequent bloggers to post more by emailing them a posting form or by IMing a reminder? By embedding a post-this-email button in Outlook?

I am becoming interested in the right half of the curve, people who update infrequently. Rebeccah Blood, speaking yesterday at PlaNetwork in San Francisco, suggested we may see people who prefer to update weekly or do a thorough refresh monthly, more of catch-up-check-in than write-as-you-go-off-the-cuff.
