Tomorrow is the two-week anniversary of Dan Colarusso’s last blog entry — and last day of work — at The Business Insider. After the fanfare surrounding his arrival, his departure after just four months on the job has been very quiet indeed, but does raise the question of whether and how a group blog should try to manage its contributors.

The most successful group blogs basically allow their bloggers to post when they like and what they like; they encourage an entrepeneurial, as opposed to managerial, culture. Sometimes, when the number of bloggers becomes enormous and there’s a desire for a site to be comprehensive, people managers need to be put in place. But TBI is still a very small shop, and I suspect that Henry Blodget won’t be hiring a new managing editor any time soon.
