I agree entirely with this. I'm personally very interested in seeing what other Drupal shops are up to development-wise, and Morbus has done what I think is an effective and tasteful summary. Keeping it to no more than once a month helps it from turning into spam. And the development list seems the best place for that -- it tends to get lost (for me) in Planet Drupal, and I'd not want to have to sign up for a development-shop-contribution-announcement list (or any other development-special-interest list for that matter).

Personally, I would encourage Drupal shops to do such a thing. I don't much care what sites companies are making (and you'll notice both of the Trellon announcements don't include client names or even links to the sites we've built) but rather how they're giving back which, in turn, helps the Drupal community (and me).
