It looks like you came up with a lot of the same conculsions our team did. We originally started with the idea we would be slow blogging with just a few useful posts a week.

We never imagined a blog like Off Center would take off the way it did, which is certainly not slow blogging, but we are really happy that Paul has spent the energy to build a blog reading audience. Thats the major reason we are happy to have split our blogs up. People like Paul can post as often as they like with out having to worry about burying the longer slower stories. Both are valid approaches, I tend to like slower blogs but I think thats not a majority position. Most people I know only want to look at a few blogs that act as aggregators and they don’t mind missing some stories if it saves them the trouble of sifting through all that material themselves.
